Crowdsourcing: How the National Library of the Netherlands (KB)
can use it
Opportunities and strategies for crowdsourcing in the cultural heritage
sector (GLAMs), and within the National Library of the Netherlands
(Koninklijke Bibliotheek, KB) in particular, are the focus of this paper by
Olaf Janssen, project manager for the KB.
In the first part you’ll read what crowdsourcing is, what motivates people to spend their time & money on
it and how it differs from old-school voluntary work. You’ll also learn what added value and advantages it
can bring, held against frequently mentioned downsides. Furthermore a number of tips for setting up and
running successful crowdsourced projects are given.
In part two we’ll focus on crowdsourcing within the cultural heritage sector. We distinguish six forms of
crowdsourcing within GLAMs, each illustrated by a number of examples. Using these six categories, we
evaluate why & how the National Library of the Netherlands could use the time and expertise of the
crowd to add value to its online activities.
The entire article is crowded with examples of crowdsourcing projects, both outside and inside GLAM-
territory.



Crowdsourcing?
Crowdsourcing invites large groups of anonymous volunteers to help
collectively realize an idea, product or service by contributing work,
knowledge, time or money. Contributions from all participants are welcome,
irrespective of expertise level, duration or motivation. In other words,
everybody can offer its specific talents and resources.
The starting point of the organizer is to profit from the individual contributions
of group members. The force of crowdsourcing lies within the new ways to
elicit and bundle the efforts of the public. People offering social overvalue –
the abundance of potentially useful and available, yet often hidden knowledge,
dedication and help - play key roles.
From the business perspective crowdsourcing can be defined as: outsourcing
traditional business activities to people outside the company or organization (according to Jeff Howe).
Crowdsourcing is more extreme than outsourcing – subcontracting to well-defined external partners,
usually within a formally contracted agreement and closed relationship. It is an open call to an undefined
group of volunteers to contribute to a business activity.
But according to some crowdsourcing is nothing more than a modern twist of the traditional suggestion
box.


Motivation of crowdsourcers
Participants of crowdsourcing projects are often
not primarily driven by material motivators (e.g.
earning money). More frequently they get a kick
from the underlying immaterial reward,
combining egocentric and altruistic factors. Key
ingredients in this mix include: satisfying
curiosity, seeking challenges, earning status and
getting recognition within a community, intellectual enrichment, belonging to a group, working for the
public good, or simply having fun.
Usually participants are able and motivated to contribute ideas, but contributing to the actual exploitation
of that idea is often of a different magnitude. For instance, designing a new beer recipe (‘open beer’
project) is relatively easy to do, but building a brewery and setting up distribution and marketing channels
are fully different ballgames.
Research on crowdsourcing projects has shown that many consumers consider it an increase of social
status when their ideas, software or content is used in the product development process of well-known
commercial companies.


That sounds pretty much like old-school voluntary work. Is it the same meat with different
gravy?
Nowadays small people are vertically challenged and spinsters are
“happy singles”. Similarly, crowdsourcing is basically a cool phrase for
collective voluntary work. Crowdsourcing 1.0 indeed goes back to the
old days, for instance bird counting, counting meteors or clearing
snowy roads.
Social media and modern communication tools (Twitter, Facebook,
wikis, smartphones, mobile broadband internet) have enabled human
networks to give new momentum to voluntary work under the new
name of crowdsourcing (2.0).
Characteristics and differences from ‘old’ voluntary work are among
others:
   By using social media for the open call, its reach and impact can be enormous. These worldwide
    networks go beyond the people that organizers already have on their radars.
   No musts, lost of flexibility. You do not need to become a member of an organization or club to be
    able to contribute. You can pick the projects that are just your thing. Every contribution is welcome,
    be it big or small, once, twice or many times.
   Contributions are less time and location dependant: you don’t need to be at a specific spot at a
    specific time to make a donation. On the Dutch petition site petities.nl you can be a pajama-activist
    any time you want.

Some crowdsourcing 2.0 examples (outside the heritage sector)
   All of Wikipedia                                         Dutch twitter-hashtag #dtv (“durf te vragen”
   Crowdfunding a pedestrian bridge in                       = dare to ask) to get solutions from the
    Rotterdam                                                 Twitter-community
   Counting splashed bugs on your number                    And many more….
    plate to map the spatio-temporal variation in
    insect density in the Netherlands.
   Searching for an ill-fated balloonist , or
    patrolling the US-Mexico border
   Creating open-source software
   Making your town nicer
   Collecting money from your fans to record a
    CD
Advantages & added value of crowdsourcing
For the organizing party crowdsourcing can deliver added value in multiple ways. We’ll discuss seven:
1) Tapping into knowledge & creativity outside the organization
    Because the (creative) expertise outside company walls can deliver significant added value, it is
    important for organizations to try to trap it. Lego has set up competitions where consumers can
    develop their own toys; the winning designs are produced and can be bought in regular shops. The
    winners can come from any age group, as a number of popular products now on sale were designed
    by children.
2) Direct feedback about product & services
    When a company gives the public the opportunity and space to voice
    their comments in an interactive dialogue, the organization can use this
    free user feedback to improve its products & services.
3) Stronger relation between product & consumer
    Crowdsourcing gives consumers the feeling they have a real voice in the
    products or services a company is delivering. They feel they are actively
    listened to and their ideas are taken seriously. For a moment consumers
    feel part of the organization. This generally leads to improved
    appreciation and a stronger relation between the two parties.
4) Organizations that (want to) use crowdsourcing are challenged to
   evaluate and review their existing work processes and habits, and adapt where necessary. People
   participating in crowdsourcing projects look critically at the transparency of the processes they are
   part of. This can stimulate a company to do business in smarter and more open ways.
5) Many hands make lighter & cheaper work
    Big and thus traditionally expensive jobs can be cut into small, simple activities that can be executed
    by large numbers of volunteers at (nearly) zero costs. This ways mountains can be moved and costs
    can be cut down significantly. A well-known example is Amazon’s Mechanical Turk, a modern twist to
    bob-a-job. With this mechanism companies have access to a flexible labour pool.
    Another example: to verify a real human is behind a PC, you are
    often asked to copy-type higgledy-piggledy arrays of characters - so
    called captchas - when registering on a website. Libraries can use
    this workflow in a clever way by cutting up old manuscripts that
    cannot be correctly OCRed into single words and having these copy-
    typed by humans at registration time. When enough people do this,
    you automatically get a complete OCR-file for free. Google’s reCaptcha is a much used application for
    this process.
6) Many hands make better work
    When in the example above you make sure that the same captcha is typed by multiple users
    repeatedly, the likelihood of errors diminishes. Linus' Law (in Eric Raymond’s version: with enough
    eyeballs, all bugs are shallow) also turns out to be applicable to creating web content.
7) Viral network effects, word-of-mouth advertising 2.0.
    The crucial role of social media in crowdsourcing makes it relatively easy
    to induce viral word-of-mouth advertising for your crowdsourced project
    or product. A person is more likely to meet a request for help he receives
    from a friend or family member than directly from a remote organization
    he is unfamiliar with and which was not pre-selected by his peers. The
    modern version of the Tupperware-party in other words. When
    additionally the Facebook page of the project has many Likes, it must be
    a cool thing you simply can’t afford to miss out on.
Downsides, pitfalls & points of attention
Besides its big advantages, crowdsourcing inevitably also has a number of downsides and points of
attention the organizer needs to be aware of when planning or running participatory projects with the
public. We’ll discuss four of them.
1) Keeping participants motivated
    To make a crowdsourcing activity a success (semi-)permanent motivation of participants is essential,
    especially when they are asked to contribute for longer periods of time. Sustaining the crowd’s
    motivation is not easy, the organizer is required to visually demonstrate & disseminate the
    (intermediate) results, most commonly via social media. Further preconditions are mutual respect,
    trust, openness, equality and enthusiasm; these sorts of things can only be built over time.
2) Quality and quantity of the contributions
    Crowdsourcing gives equal opportunities for everybody who wants
    to participate, you do not have to meet certain criteria. It can be
    questioned if all contributors are actually qualified for the activity
    at hand. There is a risk that a large percentage of contributions is
    low-grade; a rule of thumb is that about 75% of submissions is
    effectively unusable. Also large numbers of inferior contributions
    will give practical problems: it will take a lot of effort and time to
    hand-pick the valuable pearls from the mud. Furthermore, all
    submissions, irrespective of quality, must be published and
    communicated about with the senders. Last but not least there will be differences in style of the
    contributions, which is especially relevant in crowdsourced writing and photography projects. Fitting
    these into the overall product can be challenging.
    The quality of submissions can be influenced by giving people guidelines and templates. However, not
    all crowdsourcing projects are suitable for predefined fixed formats and guidelines can be ignored or
    misinterpreted easily. More attention for the quality of contributions can be generated by offering
    (financial) rewards and clear reward criteria.
3) Limitations in current generation of collaboration tools
    In many crowdsourcing projects the volunteer creates and submits his individual contribution via an
    online collaboration tool. The current generation of tools offer users only limited possibilities to build
    upon contributions from others and generate synergies. Positive exceptions are tools for open
    software development. In contrast, employees within companies often have direct access to the
    knowledge and experience of their co-workers when working on a collaborative project. The added
    value of crowdsourcing volunteers is likely to increase with the next generation of tools.
4) Copyright / IPR issues
    Crowdsourcing is impossible without volunteers. The rule that IPR
    developed in paid employment is automatically transferred from
    the employee to the company is not valid for crowdsourcing in
    general. In many projects the rights for exploitation of the
    contributions are often exclusively claimed by the organizing
    company. Because crowdsourcing is a relatively new phenomenon,
    many participants are not (yet) aware of the copyrights on their
    contributions. With the rise of new, low-barrier licensing models
    such as Creative Commons, more people will become aware of the
    role of IPR in crowdsourcing. The widespread use of these open forms of licensing can have limiting
    effects on the possibilities for exploiting the results by commercial companies.
    Another copyright-related problem that might occur in certain crowdsourcing projects is the
    uncertainly if the person contributing an idea is actually the inventor of that idea, he might as well
    have copied (or stolen) it. It can take a lot of time & effort to find out who is the legitimate owner.
Tips for successful crowdsourcing
When initiating and planning crowdsourcing projects, an organizing party can learn important lessons
from the mistakes others made before. The following best-practice tips can contribute to delivering
successful projects.
1) Be clear who you are, who you are looking for & what you expect from the project
    If you are a well-known, big organization the crowd is quite likely to be interested to be involved in
    your activities. See for instance NASA’s Ice Hunters project. But what if your are not that well-known?
    How do you find volunteers that are interested and motivated to collaborate with you? The first step
    is to explain to your potential helpers who you are, what your background & values are, what you
    want to achieve with your project and what sort of volunteers you are looking for. Are you looking for
    that single person with exactly the right bit of special expertise, or do you need to mobilize as many
    people as possible?
2) Make sure you have enough time & money
    Mobilizing the public is not possible without resources and effort. The contributions from volunteers
    might be free in themselves, but you will (nearly) always need some form of central organization to
    start, plan, execute & evaluate the project and to transform the contributions into usable products or
    services. If you want to be taken seriously by your crowd, make sure you have a solid approach and
    communication during all phases of the project. Also make sure to have enough people and resources
    available within your organization.
3) Be prepared for success
    Always expect your project to become a success right from the start. So at the beginning already
    answer “questions for later”, such as:
    -   Imagine we indeed get a solution to our problem from the crowd, how are we going to follow it
        up within the existing organizational structures?
    -   Is there a budget for follow-on?
    -   How are we going to deal with a patent the project might bring us?
4) Pick the right crowd
    In step 1 you already decided what type of crowd you
    need. If they are not Joe and Mary Citizen, we could
    speak about elite-sourcing or expert-sourcing, in other
    words: crowdsourcing with the right crowd. Selecting
    volunteers from already developed communities that
    collectively want to commit to the project is strongly
    recommended. In other words, avoid trying to set up a
    new community especially for the project. By working
    with the right, involved volunteers you’ll diminish the
    likelihood of unusable results. You’ll also need less
    moderation, which makes the joint process more
    efficient.
5) Use the right style, be to the point in your communication
   Every type of organization has it’s own specific jargon. If you want to engage with the general public,
   an outsider must be able to understand what you are talking about. Also realize that nowadays online
   means “little time, always in a hurry and a short attention span”. Therefore use a style of
   communication that is simple, to the point, generic and visually oriented; this will make it easier for
   specialists from other disciplines to get your point and feel stimulated to give their input. Obviously,
   don’t limit yourself to your own language & country, the size of the crowd will increase dramatically
   by communicating in English.
6) Have an excellent collaboration website
    A collaboration website is an excellent facilitating tool for a
    crowdsourcing project. Important requirements include:
    -    Complete integration with Twitter, Facebook and other
         social media
    -    Clear explanation which incentives the participants or
         winner(s) will get. This can be something material, or for
         instance the promise the winning ideas will be visible in a
         product or service.
    -    The site has to show lots of activity and radiate a lively
         atmosphere. This will support the required dynamic nature
         of the collaboration. Participants are the heroes in their own epic journeys and are motivated by
         guaranteed and frequent feedback about the runnings of the project.
    -    Contributions from participants must be presented in a clear and attractive way that will invite
         others to add their own solutions and build upon the contributions already submitted.
    An excellent example of a good collaboration site is My Starbucks Idea, where clients can contribute
    their product, experience & involvements ideas. The best ideas are actually taken into production.
7) Use review-experts
    It’s their task to review and assess the business value of the contributions that are being submitted.
    These reviewers can come from inside the organization, but might also be found externally via expert-
    sourcing.

The above overview is of course limited. Jasper Visser, author of the very interesting blog The Museum of
the Future, has made a list of 30 do’s for designing successful participatory and crowdsourcing projects.



Zooming in: crowdsourcing & the cultural sector (GLAMs)
Within the Dutch cultural heritage sector crowdsourcing is currently a highly trending topic. In the light of
ever decreasing government funding many GLAMS are increasingly looking at how the public can be
mobilized to support their business activities.
Oomen en Aroyo, researchers from the Institute of Sound & Vision and the VU University of Amsterdam
have researched (PDF) opportunities and challenges for crowdsourcing in GLAMs. In this paper they
distinguish six ways crowdsourcing is used.
    1.    Correction and transcription: Inviting users to correct and/or transcribe outputs of digitisation
         processes, mostly images and/or OCR
            MONK, help to improve a search engine for old manuscripts
            Transcribe Bentham, transcription of 12.400 manuscripts from Jeremy Bentham, an important
             philosopher and social reformer from London (1748-1832)
            Digitalkoot, play games to give high-quality OCR to the national library of Finland (check that
             lovely brochure). Winner of the DISH
             Award 2011
            The Victoria & Albert museum asks the
             public to crop photographed versions of
             their objects.
2. Contextualisation : Adding contextual knowledge to objects, e.g. by telling stories or writing
   articles & wiki pages with contextual data.
       Description of the Book of Kells (or any other cultural treasure) on Wikipedia
       1001 Stories of Denmark. User can contribute their own stories, photos or videos about 1001
        heritage locations in Denmark. They can also read or augment submissions from other
        people. Oneindig Noord-Holland (“Infinite North-Holland”) is a similar initiative from the
        province of Noord-Holland in the Netherlands.
3. Complementing collections : Active pursuit of additional objects to be included in a (web)exhibit
   or collection.
           In the project Europeana1914-1918 the public can upload photos,
            letters, postcards, souvenirs, stories or anecdotes about WWI. It is
            also possible for them to have physical objects digitized. By using
            the expertise of the German national library and Oxford University
            Library these materials are used to complete the existing WWI-
            collection on Europeana.
           The Bruce County Museum and Cultural Centre has an elaborate
            collection of newspapers from the area around Kincardine,
            Ontario, Canada. Sadly the collection has some gaps from the
            1930s, ’40s en ’50s. The museum asks the public for help in filling
            these gaps.
           The Museum of Broken Relationships is a traveling museum to which people with broken
            hearts can submit personal belongings that remind them of their ex-loved ones. Vulgar
            exhibitionism or useful self-help?
4. Classification : Gathering or correcting descriptive metadata related to objects in a collection. Also
   known as social tagging, user generated metadata or folksonomy. In the year 2012 a widespread
   phenomenon.
           Since 2008 the Dutch National Archives have uploaded to Flickr hundreds of photos from
            their own collection and from the Spaarnestad Photo collection. Users are asked to enrich
            these objects with tags and comments. This has been very successful, so far users have
            added thousands of tags.
           The Dutch Institute for Sound & Vision has developed the online game Woordtikkertje
            (“Word-tag”). With this attractive low-barrier game users can annotate the archive of the
            Dutch TV-series Man Bijt Hond (“Man bites dog”) in a playful manner.
5. Co-curation : Using inspiration or expertise of non-professional curators to create (web)exhibits
           A good example of co-curation was Click! A crowd-curated exhibition in the Brooklyn
            Museum in summer of 2008. In line with the adagium “the expertise outside museum
            walls is greater than it is inside”, the audience was invited to select, rank and evaluate
            this photography exhibition. A similar approach was used for Split Second.
6. Crowdfunding : Cooperation of people who pool their money together to support efforts initiated
   by others. More specifically: collecting money for supporting, expanding, conserving, enriching or
   opening up the collection. During times of ever decreasing
   government funding possibly the most relevant and important
   crowd-activity GLAMs need to tackle.
           Museum Meermanno, the oldest book museum in the
            world, currently runs Boek zoekt vrouw, man en bedrijf
            (“Book wants a wife, husband and company” - a wink
            to the very popular TV-series Farmer Wants a Wife). In
            this programme both individuals and companies are
            invited to adopt a book to prevent the museum from having to close down.
    Stadsherstel Amsterdam (a Dutch company for city restoration) wants to restore the ‘Dik
                 Trom School (Dik Trom being a famous character from Dutch children’s literature) in the
                 village of Etersheim on the shores of the IJsselmeer. The money for this project is being
                 raised via crowdfunding.


Zooming in further: crowdsourcing & the KB
As we see, there are lots of GLAMs and projects that use crowdsourcing rather successfully. As can be
suspected by the large number and variety of both national and international initiatives, there is always a
worthwhile goal and a suitable form for a GLAM to collaborate with the public.
Using the six categories above we’ll now look at how and why the KB could use the knowledge and time
of the crowd to add value to its business activities and services. We’ll also see what challenges and points
for attention the KB would need to deal with.


1) Correction & transcription: Inviting users to correct and/or transcribe outputs of digitisation
processes (images and/or OCR)
Despite lots of research current OCR technologies are not yet able to
convert historical printed texts into 100% errorless full-text.
Especially when large numbers of pages are being digitized, it is
impossible for KB or even its digitisation partner Google to produce
100% correct machine readable OCR. Also this OCR will contain
structural errors, the software will only correctly recognize paragraph
headings, footnotes, musical scores, tables etc. to a limited extent.
The situation is even worse in old manuscripts or works printed in
special or historic fonts; these are often impossible for human beings
to read or understand, let alone for computers.
However, there a couple of very good reasons why the KB should
strive for high quality OCR:
-   Searchability of its full-text collections. This will not only make it
    easier for information to be found directly, but will also benefit serendipic discovery of related
    information. The user feedback after the launch of Early Dutch Books Online in May 2011 has shown
    once more that the scientific user group of the KB has an insatiable appetite for OCR that is both
    errorless and well-structured.
-   Data services/ APIs: the KB wants to pro-actively make its metadata and full-texts available via APIs
    for B2B partners and services. These stakeholders will benefit from (and expect) high-quality KB data.
The crowd could contribute to these goals by:
-   OCR correction of KB digitization output: correcting OCR errors in digitized
    print collections (books, newspapers, magazines, proceedings of Dutch
    Parliament, radio news bulletins etc.). Suitable for a broad range of people,
    provided that the correction tools are fun and intuitive to use.
-   Transcription of manuscripts: converting manuscripts into texts, preferably
    also modern interpretations that 21st century users can understand. This can
    obviously only be done by a small group of volunteers, so expert-sourcing is
    the weapon of choice here.
As far as correction & transcription is concerned, there are no publicly visible signs
of KB-initiated collaboration between KB and interested volunteers. Dutch
journalist and language historian Ewoud Sanders: “Millions of pages from historic
newspapers, magazines and books have been put online by Dutch heritage
institutions. Because these texts have been produced by OCR, they often abound with errors. I’ve
searched for possibilities for the public to correct these errors, but hardly any website offers this
functionality, even for registered users. ”
If you want to mobilize the crowd for your project, you’ll at least need a visible and findable project
website. A search on Google for e.g. “ocr crowdsourcing kb national library netherlands” (in multiple
permutations) gives only a reference to the CONCERT tool from the IMPACT project. The KB has done an
internal pilot with this tool, but follow-on actions never happened.
For these reasons the following suggestions and points for attention are relevant :
-   Make the tools fun and intuitive to use. A good OCR correction tool should work logically without
    much explanation. Also it must be fun and engaging enough for users to want to use it again. The
    award winning Digitalkoot game mentioned earlier is an excellent example.
-   Or choose to integrate OCR correction into established workflows people already use, such as
    registering on websites using captchas.
-   Adapt the digitisation workflow of the KB for processing user-corrected texts. Apart from processing
    the user-adapted text files themselves, also the ALTO-files (which contain word coordinates for
    highlighting purposes) and search indices must be updated accordingly. Version management and
    quality control are disciplines that also need attention.


2) Contextualization: Adding contextual knowledge to objects, e.g. by telling stories or writing articles
/ Wiki pages with contextual data
The KB is the custodian of wonderful collections and objects. It tries to give
context to them in the form of e.g. dossiers, web-exhibitions, flipbooks, collection
descriptions and Historic Newspaper themes. Given the size of the KB collections
and the very limited number of collection specialists responsible for writing them,
these contextual stories are unavoidably (but well-meant) drops in the ocean. The
KB has enough materials for hundreds of person-years of writing context and
background information.
In the long-tail of the internet there are very likely enough people with sufficient
expertise, time and commitment for reliably enriching objects & (sub)collections
of the KB. The very presence of relevant lemmas on Wikipedia – a long-tail site
pur sang – and the large number of sites maintained by “Dutch written heritage
aficionados” (just some examples) strengthen this suspicion. Among them must
be enough persons that are actually prepared to enrich the KB-dossiers, write
extra explanatory texts for the flipbooks or tell their own stories and memories about events mentioned in
the KB Historic Newspapers.
As far as creating context is concerned, at this moment there are no publicly visible signs of KB-initiated
collaborations between KB and interested volunteers. The contextual KB services (dossiers,
webexhibitions, flipbooks, Dutch poet profiles) and the KB full-text websites are all based on the web1.0
one-way broadcasting model (“KB provides, users consume”). There are no possibilities whatsoever for
fans of Dutch poetry to make additions to or even remarks on existing poet profiles, or create new profiles
about their favorite poets themselves. Also, a search on Google reveals that there are no separate
crowdsourcing sites or blogs where fans of e.g. the Dutch poet H.H. ter Balkt or mythological creatures
are invited, stimulated or enabled to contribute extra context to the KB-collections.
In my previous article Wikipedia, Wikimedia, GLAMwiki - What can a GLAM do with them? (Dutch only,
English translation will follow a.s.a.p.) I already gave a number of suggestions how the KB can capture
the contextual knowledge of the crowd:
    -   Integrate the KB-dossiers into existing Wikipedia articles and create new ones where necessary.
        Consider these to be the “master” versions that are maintained, enriched and checked centrally
        by crowdsourcing. By using the available Wikipedia-APIs it is very simple to embed these Wiki-
        dossiers into the KB website.
-   The KB as serving leader within networks of Dutch culture, history &
        society aficionados. The fact that the KB is a party with established
        authority that can play a coordinating and facilitating role within these
        networks, is a key element for success.
    -   Furthermore, the KB can invest in external network facilitators. The British
        Museum has had much benefit from its Wikipedian-in-residence
        programme for improving the contextualization of its collections by Wiki-
        volunteers.
    -   The KB can make an investment in tools for capturing the contextual
        wisdom of the crowd. That can be fairly simple, for instance see how the
        Dutch Institute for Sound a & Vision has set up its Wiki-based open collaborative knowledge
        platform.
    -   The articles in the web exhibition The ideal book, one hundred years of private press in the
        Netherlands, 1910-2010 are very suitable to be transformed into a blog. This will not only
        increase the visibility of the content (blog entries are always high in Google rankings), but will
        also enable the public to provide extra context and background information via blog comments.
3) Complementing collections: Active pursuit of additional objects to be included in a (web)exhibit or
collection.
Although the physical collections of the KB are vast, they are not complete. Last year I heard it is
estimated that 1 million Dutch books (i.e. books that are written in Dutch, are about the Netherlands or
have been published in the Netherlands) are not part of the KB collection, either by deliberate choice (as
they do not fit into the acquisition strategy) or by undeliberate accident (e.g. they are not available on the
market for purchase or KB does not know about their existence). Because the KB has a national “last-
resort” deposit function, it should try to fill these undeliberate gaps. For this a call for help to the public
could be of great added value.
Actively involving the public to try to complete the collections of the KB
has not happened so far. The KB describes how publishers,
(governmental) institutions, associations or foundations can submit
publications. Although the KB also welcomes publications by individual
members of the public, no information is provided how non-publishing
citizens can donate books that are not yet part of the KB collections. A
query on Google for “Koninklijke Bibliotheek donation” (or something
similar in Dutch) gives no useable information how (and if) Average Joe
can complement KB collections.
To enable this, the KB could publish gap-lists of missing books under the slogan “KB wants a book”.
Ewoud Sanders advices to give scans of the book in return for the donation of the physical object: “I
really think this book should be part of the KB collection and would be very happy to donate it. But at the
same time I also want to be able to consult it when I need to. Is there a solution for this problem? Of
course, and it’s very obvious: I donate my paper item to the KB and I get a digitized version in return.”


4) Classification: Gathering or correcting descriptive metadata related to objects in a collection
Classic library catalogues are based on formalized and strictly controlled lists
of keywords and subject headings that have been invented by a very limited
group of library professionals. These do not necessarily match what users find
logic, handy and up-to-date. Flickr very successfully uses a bottom-up
folksonomy to enable and improve discovery of its photographs. These tags
are less formal and well-structured, but in many cases give equal or even
better, richer, more usable and multi-dimensional descriptions of the object at
hand. Successful catalogue searches are more likely when the collected tags
and logic of the community is available in addition to the formal classical top-
down taxonomy.
Users of the KB catalogues are often students, scientists or professionals. To a certain extent these
potential taggers are a group of peers, which would ensure that the user generated metadata will be and
will remain usable for these important target audiences. Based on their social tags it will be easier for the
KB to make connections to relevant websites, blog posts, films, events or online discussions.
As far as my research goes, at this moment there are no possibilities for users to tag objects they find in
KB online services. It is also not possible to correct errors yourself or to inform the KB catalogue
managers about suspected errors in the metadata. Ewoud Sanders makes the same observation in a
wider sense: “When using digital bibliographies, you will frequently find small errors. Is there an easy way
to correct these mistakes yourself? No, still not yet.”
The fear of losing control over metadata quality will be one of the reasons why there are still no
possibilities for KB users to add tags and/or correct metadata. However, to a large extent this fear is
unfounded, as user tags are always complementary to (and not instead of) the formal classifications.
Users can be offered to choice to only use the formal subject headings and ignore the social tags.
Furthermore, the social tags can be stored in a individual database, fully separated from the formal
metadata. When the KB makes sure that the user interaction for adding tags is made fun, easy and
intuitive (e.g. by game play), there are no good reasons not to make this a reality in 2012. The planned
implementation of WorldcatLocal, with its support for user tagging, seems to be a first step in the right
direction.


5) Co-curation: Using inspiration/expertise of non-professional curators to create (Web)exhibits . I’ll
limit the discussion to co-curation of KB online exhibitions.
KB’s current webexhibits show the richness of the KB collections using
treasures that have been selected and contextualized by KB’s
professional curators (collection specialists). This “view of the
professional” inevitably gives a one-dimensional perspective to these
exhibitions. After all, there is no possibility for the intended
consumers of these products to have an influence on the selection,
arrangement, connection, contextualization (see item 2 above) or
presentation of the objects prior or during the exhibition. Also there is
no possibility while visiting the exhibition to share the objects that
catch your attention within your social & professional networks. This
prevents easy and low-barrier discovery of the exhibits by new
potential audiences.
In line with Joy’s Law (“expertise outside KB walls is greater than it is
within”), there will almost certainly be enough people with sufficient commitment, time and expertise in
the long tail of the internet that are keen to co-create an online exhibition with the KB. Think of secondary
schools for instance (“the choice of the Rembrandt College”). They can shed an alternative & fresh light
on KB collections, which might very well lead to unexpected perspectives and discoveries. Furthermore,
these guest curators, just like Wikipedians-in-residence, can be used as KB ambassadors for building
bridges towards new audiences.
Of course varying degrees of freedom and collaboration are possible in this type of activity. The KB can
outsource the entire exhibition process to volunteers, from selection, digitization, arrangement,
connection, contextualization, presentation to evaluation, with the KB only supplying raw source materials
from its collections and minimum levels of organizational support. But also single process steps can be
crowdsourced, such as only the selection of the objects for instance. The KB might want to put certain
conditions on this, such as theme, geographical area, event or time period the exhibits should fit into.


6) Crowdfunding : Cooperation of people who pool their money together to support efforts initiated by
others. More specifically: collecting money for supporting, expanding, conserving, enriching or opening up
the collection.
As the KB is subject to annual budget cuts for the coming years, crowdfunding can be an interesting
option to generate extra revenue. Not so much for structural expenses in the first place, but more for e.g.
raising a supplementary amount of money for the acquisition of this one extraordinary manuscript still
missing from the collection (just like the Louvre).
Besides the direct effect (money) crowdfunding can bring indirect advantages to the KB, as it is a
mechanism to establish a long-term relationship with the public. People who make donations act as
ambassadors, they’ll tell their friends about their good deed(s) and can enthusiasmize potential new
donors outside the already known KB networks. In other words, crowdfunding can enlarge and strengthen
the networks of the KB; the more Friends of the KB, the more brand recognition, commitment, potential
new future benefactors etc.
Furthermore it can offer a lot of financial flexibility, as in crowdfunding
projects communication with the donors is very direct and transparent.
Traditional providers of subsidy budgets will account the KB against mutually
agreed fixed outcomes. Crowdfunded projects can be more flexible in their
end results as donors have only a limited say in the exact outcomes. This is
especially true when the KB manages to establish a relation of trust with its donors; it can then allow for
some freedom in the use of the crowdfunded resources, albeit within reasonable boundary conditions of
course.
The KB uses crowdfunding 1.0 on a limited scale. For the acquisition of extraordinary objects the KB calls
upon its Friends Association, which has been supporting these kind of activities for many years. Besides
this single webpage there is a remarkable lack of sites or crowdfunding platforms (that is: I cant’ find
them via Google) on which the KB pro-actively and visibly calls upon non-Friends to contribute money for
the preservation of Dutch cultural heritage.

Crowdsourcing: How the National Library of the Netherlands (KB) can use it

  • 1. Crowdsourcing: How the National Library of the Netherlands (KB) can use it Opportunities and strategies for crowdsourcing in the cultural heritage sector (GLAMs), and within the National Library of the Netherlands (Koninklijke Bibliotheek, KB) in particular, are the focus of this paper by Olaf Janssen, project manager for the KB. In the first part you’ll read what crowdsourcing is, what motivates people to spend their time & money on it and how it differs from old-school voluntary work. You’ll also learn what added value and advantages it can bring, held against frequently mentioned downsides. Furthermore a number of tips for setting up and running successful crowdsourced projects are given. In part two we’ll focus on crowdsourcing within the cultural heritage sector. We distinguish six forms of crowdsourcing within GLAMs, each illustrated by a number of examples. Using these six categories, we evaluate why & how the National Library of the Netherlands could use the time and expertise of the crowd to add value to its online activities. The entire article is crowded with examples of crowdsourcing projects, both outside and inside GLAM- territory. Crowdsourcing? Crowdsourcing invites large groups of anonymous volunteers to help collectively realize an idea, product or service by contributing work, knowledge, time or money. Contributions from all participants are welcome, irrespective of expertise level, duration or motivation. In other words, everybody can offer its specific talents and resources. The starting point of the organizer is to profit from the individual contributions of group members. The force of crowdsourcing lies within the new ways to elicit and bundle the efforts of the public. People offering social overvalue – the abundance of potentially useful and available, yet often hidden knowledge, dedication and help - play key roles. From the business perspective crowdsourcing can be defined as: outsourcing traditional business activities to people outside the company or organization (according to Jeff Howe). Crowdsourcing is more extreme than outsourcing – subcontracting to well-defined external partners, usually within a formally contracted agreement and closed relationship. It is an open call to an undefined group of volunteers to contribute to a business activity. But according to some crowdsourcing is nothing more than a modern twist of the traditional suggestion box. Motivation of crowdsourcers Participants of crowdsourcing projects are often not primarily driven by material motivators (e.g. earning money). More frequently they get a kick from the underlying immaterial reward, combining egocentric and altruistic factors. Key ingredients in this mix include: satisfying curiosity, seeking challenges, earning status and getting recognition within a community, intellectual enrichment, belonging to a group, working for the public good, or simply having fun.
  • 2. Usually participants are able and motivated to contribute ideas, but contributing to the actual exploitation of that idea is often of a different magnitude. For instance, designing a new beer recipe (‘open beer’ project) is relatively easy to do, but building a brewery and setting up distribution and marketing channels are fully different ballgames. Research on crowdsourcing projects has shown that many consumers consider it an increase of social status when their ideas, software or content is used in the product development process of well-known commercial companies. That sounds pretty much like old-school voluntary work. Is it the same meat with different gravy? Nowadays small people are vertically challenged and spinsters are “happy singles”. Similarly, crowdsourcing is basically a cool phrase for collective voluntary work. Crowdsourcing 1.0 indeed goes back to the old days, for instance bird counting, counting meteors or clearing snowy roads. Social media and modern communication tools (Twitter, Facebook, wikis, smartphones, mobile broadband internet) have enabled human networks to give new momentum to voluntary work under the new name of crowdsourcing (2.0). Characteristics and differences from ‘old’ voluntary work are among others:  By using social media for the open call, its reach and impact can be enormous. These worldwide networks go beyond the people that organizers already have on their radars.  No musts, lost of flexibility. You do not need to become a member of an organization or club to be able to contribute. You can pick the projects that are just your thing. Every contribution is welcome, be it big or small, once, twice or many times.  Contributions are less time and location dependant: you don’t need to be at a specific spot at a specific time to make a donation. On the Dutch petition site petities.nl you can be a pajama-activist any time you want. Some crowdsourcing 2.0 examples (outside the heritage sector)  All of Wikipedia  Dutch twitter-hashtag #dtv (“durf te vragen”  Crowdfunding a pedestrian bridge in = dare to ask) to get solutions from the Rotterdam Twitter-community  Counting splashed bugs on your number  And many more…. plate to map the spatio-temporal variation in insect density in the Netherlands.  Searching for an ill-fated balloonist , or patrolling the US-Mexico border  Creating open-source software  Making your town nicer  Collecting money from your fans to record a CD
  • 3. Advantages & added value of crowdsourcing For the organizing party crowdsourcing can deliver added value in multiple ways. We’ll discuss seven: 1) Tapping into knowledge & creativity outside the organization Because the (creative) expertise outside company walls can deliver significant added value, it is important for organizations to try to trap it. Lego has set up competitions where consumers can develop their own toys; the winning designs are produced and can be bought in regular shops. The winners can come from any age group, as a number of popular products now on sale were designed by children. 2) Direct feedback about product & services When a company gives the public the opportunity and space to voice their comments in an interactive dialogue, the organization can use this free user feedback to improve its products & services. 3) Stronger relation between product & consumer Crowdsourcing gives consumers the feeling they have a real voice in the products or services a company is delivering. They feel they are actively listened to and their ideas are taken seriously. For a moment consumers feel part of the organization. This generally leads to improved appreciation and a stronger relation between the two parties. 4) Organizations that (want to) use crowdsourcing are challenged to evaluate and review their existing work processes and habits, and adapt where necessary. People participating in crowdsourcing projects look critically at the transparency of the processes they are part of. This can stimulate a company to do business in smarter and more open ways. 5) Many hands make lighter & cheaper work Big and thus traditionally expensive jobs can be cut into small, simple activities that can be executed by large numbers of volunteers at (nearly) zero costs. This ways mountains can be moved and costs can be cut down significantly. A well-known example is Amazon’s Mechanical Turk, a modern twist to bob-a-job. With this mechanism companies have access to a flexible labour pool. Another example: to verify a real human is behind a PC, you are often asked to copy-type higgledy-piggledy arrays of characters - so called captchas - when registering on a website. Libraries can use this workflow in a clever way by cutting up old manuscripts that cannot be correctly OCRed into single words and having these copy- typed by humans at registration time. When enough people do this, you automatically get a complete OCR-file for free. Google’s reCaptcha is a much used application for this process. 6) Many hands make better work When in the example above you make sure that the same captcha is typed by multiple users repeatedly, the likelihood of errors diminishes. Linus' Law (in Eric Raymond’s version: with enough eyeballs, all bugs are shallow) also turns out to be applicable to creating web content. 7) Viral network effects, word-of-mouth advertising 2.0. The crucial role of social media in crowdsourcing makes it relatively easy to induce viral word-of-mouth advertising for your crowdsourced project or product. A person is more likely to meet a request for help he receives from a friend or family member than directly from a remote organization he is unfamiliar with and which was not pre-selected by his peers. The modern version of the Tupperware-party in other words. When additionally the Facebook page of the project has many Likes, it must be a cool thing you simply can’t afford to miss out on.
  • 4. Downsides, pitfalls & points of attention Besides its big advantages, crowdsourcing inevitably also has a number of downsides and points of attention the organizer needs to be aware of when planning or running participatory projects with the public. We’ll discuss four of them. 1) Keeping participants motivated To make a crowdsourcing activity a success (semi-)permanent motivation of participants is essential, especially when they are asked to contribute for longer periods of time. Sustaining the crowd’s motivation is not easy, the organizer is required to visually demonstrate & disseminate the (intermediate) results, most commonly via social media. Further preconditions are mutual respect, trust, openness, equality and enthusiasm; these sorts of things can only be built over time. 2) Quality and quantity of the contributions Crowdsourcing gives equal opportunities for everybody who wants to participate, you do not have to meet certain criteria. It can be questioned if all contributors are actually qualified for the activity at hand. There is a risk that a large percentage of contributions is low-grade; a rule of thumb is that about 75% of submissions is effectively unusable. Also large numbers of inferior contributions will give practical problems: it will take a lot of effort and time to hand-pick the valuable pearls from the mud. Furthermore, all submissions, irrespective of quality, must be published and communicated about with the senders. Last but not least there will be differences in style of the contributions, which is especially relevant in crowdsourced writing and photography projects. Fitting these into the overall product can be challenging. The quality of submissions can be influenced by giving people guidelines and templates. However, not all crowdsourcing projects are suitable for predefined fixed formats and guidelines can be ignored or misinterpreted easily. More attention for the quality of contributions can be generated by offering (financial) rewards and clear reward criteria. 3) Limitations in current generation of collaboration tools In many crowdsourcing projects the volunteer creates and submits his individual contribution via an online collaboration tool. The current generation of tools offer users only limited possibilities to build upon contributions from others and generate synergies. Positive exceptions are tools for open software development. In contrast, employees within companies often have direct access to the knowledge and experience of their co-workers when working on a collaborative project. The added value of crowdsourcing volunteers is likely to increase with the next generation of tools. 4) Copyright / IPR issues Crowdsourcing is impossible without volunteers. The rule that IPR developed in paid employment is automatically transferred from the employee to the company is not valid for crowdsourcing in general. In many projects the rights for exploitation of the contributions are often exclusively claimed by the organizing company. Because crowdsourcing is a relatively new phenomenon, many participants are not (yet) aware of the copyrights on their contributions. With the rise of new, low-barrier licensing models such as Creative Commons, more people will become aware of the role of IPR in crowdsourcing. The widespread use of these open forms of licensing can have limiting effects on the possibilities for exploiting the results by commercial companies. Another copyright-related problem that might occur in certain crowdsourcing projects is the uncertainly if the person contributing an idea is actually the inventor of that idea, he might as well have copied (or stolen) it. It can take a lot of time & effort to find out who is the legitimate owner.
  • 5. Tips for successful crowdsourcing When initiating and planning crowdsourcing projects, an organizing party can learn important lessons from the mistakes others made before. The following best-practice tips can contribute to delivering successful projects. 1) Be clear who you are, who you are looking for & what you expect from the project If you are a well-known, big organization the crowd is quite likely to be interested to be involved in your activities. See for instance NASA’s Ice Hunters project. But what if your are not that well-known? How do you find volunteers that are interested and motivated to collaborate with you? The first step is to explain to your potential helpers who you are, what your background & values are, what you want to achieve with your project and what sort of volunteers you are looking for. Are you looking for that single person with exactly the right bit of special expertise, or do you need to mobilize as many people as possible? 2) Make sure you have enough time & money Mobilizing the public is not possible without resources and effort. The contributions from volunteers might be free in themselves, but you will (nearly) always need some form of central organization to start, plan, execute & evaluate the project and to transform the contributions into usable products or services. If you want to be taken seriously by your crowd, make sure you have a solid approach and communication during all phases of the project. Also make sure to have enough people and resources available within your organization. 3) Be prepared for success Always expect your project to become a success right from the start. So at the beginning already answer “questions for later”, such as: - Imagine we indeed get a solution to our problem from the crowd, how are we going to follow it up within the existing organizational structures? - Is there a budget for follow-on? - How are we going to deal with a patent the project might bring us? 4) Pick the right crowd In step 1 you already decided what type of crowd you need. If they are not Joe and Mary Citizen, we could speak about elite-sourcing or expert-sourcing, in other words: crowdsourcing with the right crowd. Selecting volunteers from already developed communities that collectively want to commit to the project is strongly recommended. In other words, avoid trying to set up a new community especially for the project. By working with the right, involved volunteers you’ll diminish the likelihood of unusable results. You’ll also need less moderation, which makes the joint process more efficient. 5) Use the right style, be to the point in your communication Every type of organization has it’s own specific jargon. If you want to engage with the general public, an outsider must be able to understand what you are talking about. Also realize that nowadays online means “little time, always in a hurry and a short attention span”. Therefore use a style of communication that is simple, to the point, generic and visually oriented; this will make it easier for specialists from other disciplines to get your point and feel stimulated to give their input. Obviously, don’t limit yourself to your own language & country, the size of the crowd will increase dramatically by communicating in English.
  • 6. 6) Have an excellent collaboration website A collaboration website is an excellent facilitating tool for a crowdsourcing project. Important requirements include: - Complete integration with Twitter, Facebook and other social media - Clear explanation which incentives the participants or winner(s) will get. This can be something material, or for instance the promise the winning ideas will be visible in a product or service. - The site has to show lots of activity and radiate a lively atmosphere. This will support the required dynamic nature of the collaboration. Participants are the heroes in their own epic journeys and are motivated by guaranteed and frequent feedback about the runnings of the project. - Contributions from participants must be presented in a clear and attractive way that will invite others to add their own solutions and build upon the contributions already submitted. An excellent example of a good collaboration site is My Starbucks Idea, where clients can contribute their product, experience & involvements ideas. The best ideas are actually taken into production. 7) Use review-experts It’s their task to review and assess the business value of the contributions that are being submitted. These reviewers can come from inside the organization, but might also be found externally via expert- sourcing. The above overview is of course limited. Jasper Visser, author of the very interesting blog The Museum of the Future, has made a list of 30 do’s for designing successful participatory and crowdsourcing projects. Zooming in: crowdsourcing & the cultural sector (GLAMs) Within the Dutch cultural heritage sector crowdsourcing is currently a highly trending topic. In the light of ever decreasing government funding many GLAMS are increasingly looking at how the public can be mobilized to support their business activities. Oomen en Aroyo, researchers from the Institute of Sound & Vision and the VU University of Amsterdam have researched (PDF) opportunities and challenges for crowdsourcing in GLAMs. In this paper they distinguish six ways crowdsourcing is used. 1. Correction and transcription: Inviting users to correct and/or transcribe outputs of digitisation processes, mostly images and/or OCR  MONK, help to improve a search engine for old manuscripts  Transcribe Bentham, transcription of 12.400 manuscripts from Jeremy Bentham, an important philosopher and social reformer from London (1748-1832)  Digitalkoot, play games to give high-quality OCR to the national library of Finland (check that lovely brochure). Winner of the DISH Award 2011  The Victoria & Albert museum asks the public to crop photographed versions of their objects.
  • 7. 2. Contextualisation : Adding contextual knowledge to objects, e.g. by telling stories or writing articles & wiki pages with contextual data.  Description of the Book of Kells (or any other cultural treasure) on Wikipedia  1001 Stories of Denmark. User can contribute their own stories, photos or videos about 1001 heritage locations in Denmark. They can also read or augment submissions from other people. Oneindig Noord-Holland (“Infinite North-Holland”) is a similar initiative from the province of Noord-Holland in the Netherlands. 3. Complementing collections : Active pursuit of additional objects to be included in a (web)exhibit or collection.  In the project Europeana1914-1918 the public can upload photos, letters, postcards, souvenirs, stories or anecdotes about WWI. It is also possible for them to have physical objects digitized. By using the expertise of the German national library and Oxford University Library these materials are used to complete the existing WWI- collection on Europeana.  The Bruce County Museum and Cultural Centre has an elaborate collection of newspapers from the area around Kincardine, Ontario, Canada. Sadly the collection has some gaps from the 1930s, ’40s en ’50s. The museum asks the public for help in filling these gaps.  The Museum of Broken Relationships is a traveling museum to which people with broken hearts can submit personal belongings that remind them of their ex-loved ones. Vulgar exhibitionism or useful self-help? 4. Classification : Gathering or correcting descriptive metadata related to objects in a collection. Also known as social tagging, user generated metadata or folksonomy. In the year 2012 a widespread phenomenon.  Since 2008 the Dutch National Archives have uploaded to Flickr hundreds of photos from their own collection and from the Spaarnestad Photo collection. Users are asked to enrich these objects with tags and comments. This has been very successful, so far users have added thousands of tags.  The Dutch Institute for Sound & Vision has developed the online game Woordtikkertje (“Word-tag”). With this attractive low-barrier game users can annotate the archive of the Dutch TV-series Man Bijt Hond (“Man bites dog”) in a playful manner. 5. Co-curation : Using inspiration or expertise of non-professional curators to create (web)exhibits  A good example of co-curation was Click! A crowd-curated exhibition in the Brooklyn Museum in summer of 2008. In line with the adagium “the expertise outside museum walls is greater than it is inside”, the audience was invited to select, rank and evaluate this photography exhibition. A similar approach was used for Split Second. 6. Crowdfunding : Cooperation of people who pool their money together to support efforts initiated by others. More specifically: collecting money for supporting, expanding, conserving, enriching or opening up the collection. During times of ever decreasing government funding possibly the most relevant and important crowd-activity GLAMs need to tackle.  Museum Meermanno, the oldest book museum in the world, currently runs Boek zoekt vrouw, man en bedrijf (“Book wants a wife, husband and company” - a wink to the very popular TV-series Farmer Wants a Wife). In this programme both individuals and companies are invited to adopt a book to prevent the museum from having to close down.
  • 8. Stadsherstel Amsterdam (a Dutch company for city restoration) wants to restore the ‘Dik Trom School (Dik Trom being a famous character from Dutch children’s literature) in the village of Etersheim on the shores of the IJsselmeer. The money for this project is being raised via crowdfunding. Zooming in further: crowdsourcing & the KB As we see, there are lots of GLAMs and projects that use crowdsourcing rather successfully. As can be suspected by the large number and variety of both national and international initiatives, there is always a worthwhile goal and a suitable form for a GLAM to collaborate with the public. Using the six categories above we’ll now look at how and why the KB could use the knowledge and time of the crowd to add value to its business activities and services. We’ll also see what challenges and points for attention the KB would need to deal with. 1) Correction & transcription: Inviting users to correct and/or transcribe outputs of digitisation processes (images and/or OCR) Despite lots of research current OCR technologies are not yet able to convert historical printed texts into 100% errorless full-text. Especially when large numbers of pages are being digitized, it is impossible for KB or even its digitisation partner Google to produce 100% correct machine readable OCR. Also this OCR will contain structural errors, the software will only correctly recognize paragraph headings, footnotes, musical scores, tables etc. to a limited extent. The situation is even worse in old manuscripts or works printed in special or historic fonts; these are often impossible for human beings to read or understand, let alone for computers. However, there a couple of very good reasons why the KB should strive for high quality OCR: - Searchability of its full-text collections. This will not only make it easier for information to be found directly, but will also benefit serendipic discovery of related information. The user feedback after the launch of Early Dutch Books Online in May 2011 has shown once more that the scientific user group of the KB has an insatiable appetite for OCR that is both errorless and well-structured. - Data services/ APIs: the KB wants to pro-actively make its metadata and full-texts available via APIs for B2B partners and services. These stakeholders will benefit from (and expect) high-quality KB data. The crowd could contribute to these goals by: - OCR correction of KB digitization output: correcting OCR errors in digitized print collections (books, newspapers, magazines, proceedings of Dutch Parliament, radio news bulletins etc.). Suitable for a broad range of people, provided that the correction tools are fun and intuitive to use. - Transcription of manuscripts: converting manuscripts into texts, preferably also modern interpretations that 21st century users can understand. This can obviously only be done by a small group of volunteers, so expert-sourcing is the weapon of choice here. As far as correction & transcription is concerned, there are no publicly visible signs of KB-initiated collaboration between KB and interested volunteers. Dutch journalist and language historian Ewoud Sanders: “Millions of pages from historic newspapers, magazines and books have been put online by Dutch heritage
  • 9. institutions. Because these texts have been produced by OCR, they often abound with errors. I’ve searched for possibilities for the public to correct these errors, but hardly any website offers this functionality, even for registered users. ” If you want to mobilize the crowd for your project, you’ll at least need a visible and findable project website. A search on Google for e.g. “ocr crowdsourcing kb national library netherlands” (in multiple permutations) gives only a reference to the CONCERT tool from the IMPACT project. The KB has done an internal pilot with this tool, but follow-on actions never happened. For these reasons the following suggestions and points for attention are relevant : - Make the tools fun and intuitive to use. A good OCR correction tool should work logically without much explanation. Also it must be fun and engaging enough for users to want to use it again. The award winning Digitalkoot game mentioned earlier is an excellent example. - Or choose to integrate OCR correction into established workflows people already use, such as registering on websites using captchas. - Adapt the digitisation workflow of the KB for processing user-corrected texts. Apart from processing the user-adapted text files themselves, also the ALTO-files (which contain word coordinates for highlighting purposes) and search indices must be updated accordingly. Version management and quality control are disciplines that also need attention. 2) Contextualization: Adding contextual knowledge to objects, e.g. by telling stories or writing articles / Wiki pages with contextual data The KB is the custodian of wonderful collections and objects. It tries to give context to them in the form of e.g. dossiers, web-exhibitions, flipbooks, collection descriptions and Historic Newspaper themes. Given the size of the KB collections and the very limited number of collection specialists responsible for writing them, these contextual stories are unavoidably (but well-meant) drops in the ocean. The KB has enough materials for hundreds of person-years of writing context and background information. In the long-tail of the internet there are very likely enough people with sufficient expertise, time and commitment for reliably enriching objects & (sub)collections of the KB. The very presence of relevant lemmas on Wikipedia – a long-tail site pur sang – and the large number of sites maintained by “Dutch written heritage aficionados” (just some examples) strengthen this suspicion. Among them must be enough persons that are actually prepared to enrich the KB-dossiers, write extra explanatory texts for the flipbooks or tell their own stories and memories about events mentioned in the KB Historic Newspapers. As far as creating context is concerned, at this moment there are no publicly visible signs of KB-initiated collaborations between KB and interested volunteers. The contextual KB services (dossiers, webexhibitions, flipbooks, Dutch poet profiles) and the KB full-text websites are all based on the web1.0 one-way broadcasting model (“KB provides, users consume”). There are no possibilities whatsoever for fans of Dutch poetry to make additions to or even remarks on existing poet profiles, or create new profiles about their favorite poets themselves. Also, a search on Google reveals that there are no separate crowdsourcing sites or blogs where fans of e.g. the Dutch poet H.H. ter Balkt or mythological creatures are invited, stimulated or enabled to contribute extra context to the KB-collections. In my previous article Wikipedia, Wikimedia, GLAMwiki - What can a GLAM do with them? (Dutch only, English translation will follow a.s.a.p.) I already gave a number of suggestions how the KB can capture the contextual knowledge of the crowd: - Integrate the KB-dossiers into existing Wikipedia articles and create new ones where necessary. Consider these to be the “master” versions that are maintained, enriched and checked centrally by crowdsourcing. By using the available Wikipedia-APIs it is very simple to embed these Wiki- dossiers into the KB website.
  • 10. - The KB as serving leader within networks of Dutch culture, history & society aficionados. The fact that the KB is a party with established authority that can play a coordinating and facilitating role within these networks, is a key element for success. - Furthermore, the KB can invest in external network facilitators. The British Museum has had much benefit from its Wikipedian-in-residence programme for improving the contextualization of its collections by Wiki- volunteers. - The KB can make an investment in tools for capturing the contextual wisdom of the crowd. That can be fairly simple, for instance see how the Dutch Institute for Sound a & Vision has set up its Wiki-based open collaborative knowledge platform. - The articles in the web exhibition The ideal book, one hundred years of private press in the Netherlands, 1910-2010 are very suitable to be transformed into a blog. This will not only increase the visibility of the content (blog entries are always high in Google rankings), but will also enable the public to provide extra context and background information via blog comments. 3) Complementing collections: Active pursuit of additional objects to be included in a (web)exhibit or collection. Although the physical collections of the KB are vast, they are not complete. Last year I heard it is estimated that 1 million Dutch books (i.e. books that are written in Dutch, are about the Netherlands or have been published in the Netherlands) are not part of the KB collection, either by deliberate choice (as they do not fit into the acquisition strategy) or by undeliberate accident (e.g. they are not available on the market for purchase or KB does not know about their existence). Because the KB has a national “last- resort” deposit function, it should try to fill these undeliberate gaps. For this a call for help to the public could be of great added value. Actively involving the public to try to complete the collections of the KB has not happened so far. The KB describes how publishers, (governmental) institutions, associations or foundations can submit publications. Although the KB also welcomes publications by individual members of the public, no information is provided how non-publishing citizens can donate books that are not yet part of the KB collections. A query on Google for “Koninklijke Bibliotheek donation” (or something similar in Dutch) gives no useable information how (and if) Average Joe can complement KB collections. To enable this, the KB could publish gap-lists of missing books under the slogan “KB wants a book”. Ewoud Sanders advices to give scans of the book in return for the donation of the physical object: “I really think this book should be part of the KB collection and would be very happy to donate it. But at the same time I also want to be able to consult it when I need to. Is there a solution for this problem? Of course, and it’s very obvious: I donate my paper item to the KB and I get a digitized version in return.” 4) Classification: Gathering or correcting descriptive metadata related to objects in a collection Classic library catalogues are based on formalized and strictly controlled lists of keywords and subject headings that have been invented by a very limited group of library professionals. These do not necessarily match what users find logic, handy and up-to-date. Flickr very successfully uses a bottom-up folksonomy to enable and improve discovery of its photographs. These tags are less formal and well-structured, but in many cases give equal or even better, richer, more usable and multi-dimensional descriptions of the object at hand. Successful catalogue searches are more likely when the collected tags and logic of the community is available in addition to the formal classical top- down taxonomy.
  • 11. Users of the KB catalogues are often students, scientists or professionals. To a certain extent these potential taggers are a group of peers, which would ensure that the user generated metadata will be and will remain usable for these important target audiences. Based on their social tags it will be easier for the KB to make connections to relevant websites, blog posts, films, events or online discussions. As far as my research goes, at this moment there are no possibilities for users to tag objects they find in KB online services. It is also not possible to correct errors yourself or to inform the KB catalogue managers about suspected errors in the metadata. Ewoud Sanders makes the same observation in a wider sense: “When using digital bibliographies, you will frequently find small errors. Is there an easy way to correct these mistakes yourself? No, still not yet.” The fear of losing control over metadata quality will be one of the reasons why there are still no possibilities for KB users to add tags and/or correct metadata. However, to a large extent this fear is unfounded, as user tags are always complementary to (and not instead of) the formal classifications. Users can be offered to choice to only use the formal subject headings and ignore the social tags. Furthermore, the social tags can be stored in a individual database, fully separated from the formal metadata. When the KB makes sure that the user interaction for adding tags is made fun, easy and intuitive (e.g. by game play), there are no good reasons not to make this a reality in 2012. The planned implementation of WorldcatLocal, with its support for user tagging, seems to be a first step in the right direction. 5) Co-curation: Using inspiration/expertise of non-professional curators to create (Web)exhibits . I’ll limit the discussion to co-curation of KB online exhibitions. KB’s current webexhibits show the richness of the KB collections using treasures that have been selected and contextualized by KB’s professional curators (collection specialists). This “view of the professional” inevitably gives a one-dimensional perspective to these exhibitions. After all, there is no possibility for the intended consumers of these products to have an influence on the selection, arrangement, connection, contextualization (see item 2 above) or presentation of the objects prior or during the exhibition. Also there is no possibility while visiting the exhibition to share the objects that catch your attention within your social & professional networks. This prevents easy and low-barrier discovery of the exhibits by new potential audiences. In line with Joy’s Law (“expertise outside KB walls is greater than it is within”), there will almost certainly be enough people with sufficient commitment, time and expertise in the long tail of the internet that are keen to co-create an online exhibition with the KB. Think of secondary schools for instance (“the choice of the Rembrandt College”). They can shed an alternative & fresh light on KB collections, which might very well lead to unexpected perspectives and discoveries. Furthermore, these guest curators, just like Wikipedians-in-residence, can be used as KB ambassadors for building bridges towards new audiences. Of course varying degrees of freedom and collaboration are possible in this type of activity. The KB can outsource the entire exhibition process to volunteers, from selection, digitization, arrangement, connection, contextualization, presentation to evaluation, with the KB only supplying raw source materials from its collections and minimum levels of organizational support. But also single process steps can be crowdsourced, such as only the selection of the objects for instance. The KB might want to put certain conditions on this, such as theme, geographical area, event or time period the exhibits should fit into. 6) Crowdfunding : Cooperation of people who pool their money together to support efforts initiated by others. More specifically: collecting money for supporting, expanding, conserving, enriching or opening up the collection.
  • 12. As the KB is subject to annual budget cuts for the coming years, crowdfunding can be an interesting option to generate extra revenue. Not so much for structural expenses in the first place, but more for e.g. raising a supplementary amount of money for the acquisition of this one extraordinary manuscript still missing from the collection (just like the Louvre). Besides the direct effect (money) crowdfunding can bring indirect advantages to the KB, as it is a mechanism to establish a long-term relationship with the public. People who make donations act as ambassadors, they’ll tell their friends about their good deed(s) and can enthusiasmize potential new donors outside the already known KB networks. In other words, crowdfunding can enlarge and strengthen the networks of the KB; the more Friends of the KB, the more brand recognition, commitment, potential new future benefactors etc. Furthermore it can offer a lot of financial flexibility, as in crowdfunding projects communication with the donors is very direct and transparent. Traditional providers of subsidy budgets will account the KB against mutually agreed fixed outcomes. Crowdfunded projects can be more flexible in their end results as donors have only a limited say in the exact outcomes. This is especially true when the KB manages to establish a relation of trust with its donors; it can then allow for some freedom in the use of the crowdfunded resources, albeit within reasonable boundary conditions of course. The KB uses crowdfunding 1.0 on a limited scale. For the acquisition of extraordinary objects the KB calls upon its Friends Association, which has been supporting these kind of activities for many years. Besides this single webpage there is a remarkable lack of sites or crowdfunding platforms (that is: I cant’ find them via Google) on which the KB pro-actively and visibly calls upon non-Friends to contribute money for the preservation of Dutch cultural heritage.
