Looking for Digitised / Digital Content in the BL

•Digitisation costs time, resources & access
can depend on restrictions imposed by
funders, legal, ethical, practical etc. …
•Still…702 Digitisation projects
(as of 09/04/2018)
But not all found through search
engines or even online!
So little digitised…why?

11
Openly Licensed Digital Content?
15% Openly
Licensed
Around 80%*
available online
Working through to make more open…
Though some collections will always only be available onsite due to
various reasons including legal, ethical etc
Breakdown by collection*
Manuscripts 59%
Books 9%
Maps and Views 7%
Newspapers 3%
Archives and Records 3%
Paintings, Prints and Drawings 2%
*Based on number of digitisation projects (702 as of 09/04/18)
Largest proportion of funding
Public / Private Partnership
15 %* Openly Licensed – most online
85 %* Available onsite only at the moment

The Story of the Digital Collection…
Digital
Collection

Who paid for the digitisation?
Who did the digitisation?
Technology used
Born digital?
Published
Unpublished
Where is it?
Can it still be accessed?
Generates income
Reputational risk in using?
Legalities
Politics when digitised
Personalities involved
Surprises (e.g. gaps)
Descriptive information
Old format not supported
What media was the
digitisation done from?
Is there any background documentation?
No Descriptive information
Inconsistent descriptive information
Still there?
Good to know the background ‘Story’ of a Digital Collection’
if you want to use it for research and make conclusions…

• Dialogue typically:
– you are ‘lucky’ & we have the digital content
/ data relevant to your research
– we don’t have exactly what your looking for,
but is there anything of interest? Let’s talk…
– engagement is hard work and it’s constantly
required to maintain interest in our digital
collections!
• Artists find this dialogue easier…
• We also tend to attract researchers with ‘fuzzier’
research boundaries and possibly open to more
interdisciplinary / collaborative research
What engagement does the BL have with
researchers wanting use our digital content?

14
Open Content vs Onsite Only Access
• Access easier for openly licensed content
• More challenging for on-site, in-copyright, non-print legal
deposit, data protected, old content media & contemporary
material (post 1877)

Challenges of access to Digital Collections

18
Accessing digital collections onsite
OPEN
£
• Have to be ‘onsite’ (interpretations vary)
• Need to be ‘security cleared’ ‘trusted’ for some collections
– Hence ‘Researcher in Residence Model’
• Permission required (depending on ‘story’ of collection)
• Content could be on various media formats
(not always online)
• 5 - 20 % re-use of material for non commercial research for
some collections, depends on agreements in place
• We are learning ‘pathways’ so that this becomes ‘everyday’ to
provide onsite access to some digital collections in the future

19
Overview of interactions with the
“researcher”

www.bl.uk
Phase 1: Exploration
• Exploration phase allows a researcher to:
• understand the data in an open-ended fashion,
• discover potential tools to work with the data,
• gain awareness of their capabilities and limitations,
• develop a firmer research query and
• gauge the costs, risks and time needed.
• Outputs of the exploration are not intended to be shareable,
beyond personal experience and key features (data size, formats, tool
successes, etc).
20

www.bl.uk
Phase 2: Query-Focussed
• “Query-Focussed”, the familiar project but due to phase 1:
• A firmer and more informed query by the researcher
• Suitable datasets already lined up
• A good idea of the initial toolset and capabilities (human and computer)
required
• Project output is outlined, and relevant reuse applications are begun.
• Clear agreements on what happens at the end of the project – data
deletion, virtual machine deletion/archiving/etc.
• Project may iterate on initial ideas, depending on researcher’s cost/risk
appetite
21

www.bl.uk
Phase 3: Wrap-up
• Wrap-up
• Work (code, notes) exported and given to researcher
• All derivative data is licenced or retained based on reuse agreements
(Access & Reuse board, etc)
• Provisions made for the project are wound-down, as agreed (derivative
data deleted after a grace period, etc)

23
Why are we doing this?

24
Why are doing this? (1)
Working closely with and listening
to those who want use our digital
collections and data for their work
https://goo.gl/esqpRb

25
We can learn how we are and should be supporting them and
this therefore shapes the problems we work on, such as:
https://goo.gl/esqpRb
• Access to digital collections / data?
• Advice, guidance, technical
support, training
• Services, Tools and Processes?
• Many more reasons…

26
Where are the gaps between what users want & what we can
give?
How do we build the bridges to overcome the gaps?
https://goo.gl/6CwCeE

27
How do we help users ‘navigate’ their way through the
‘maze’ of the Library to what they want to do?
Sometimes requires understanding the culture of the organisation
https://goo.gl/62JnQT

28
Working with British Library Digitised
Newspapers
• Digitised through public / private means
• Can use commercial products to look manually for content, with search
interfaces but no APIs, useful starting point though, manual methods
can translate into computational ones
• OCR quality is not great, metadata is OK, but plenty of hidden material,
approaches require to consider this, e.g. ‘Good, Bad and Ugly’ OCR
• If you want to work on digitised items at the BL, need security clearance,
carry out exploration, write letter of intent to communicate to GALE
• Can purchase drives from GALE Cengage with content (dependent on
subscription)

29
Good, Bad, Ugly Image Quality / OCR
• Original image capture of newspaper images can effect the
quality of the OCR
• A poor image, very difficult to re-OCR
• Good image quality much better chance for re-OCR
• Bi-tonal, Grey Scale, Colour can effect the quality of the
OCR
• Methodology of working with collection at scale needs to
acknowledge OCR and image quality

30
Breaking Black Boxes – Melodee Beals

31
Burney Collection
• Gathered by the Reverend Charles Burney (1757- 1817)
• 700 volumes, newspapers and news pamphlets, published
in London, English provincial, Irish and Scottish papers, and
a few examples from the American colonies.
• 1271 titles
• Around 1 million digitised page images – from around 2006
from Microfilm
• OCR quality mixed, used custom XML format
• Bi-tonal

To favourite an image requires an account

91
Flickr Galleries
More useful if you have an account
You can create a Gallery of Flickr images to share with everyone
Gallery is tied to your account

92
Flickr Groups
Community based – for sharing and discussing images
We might create a group for the competition – watch this space!
