    20. 20. 4.0 Library catalog vs web
    21. 21. Is internet replacing library? <ul><li>In History, we had to do this project on Tokoh [prominent personality]. When I went to the Internet – and it had more things, like biography, like more picture, certificates and awards – that kind of stuff. So it made it like easier to write and I got good grade on my assignment. </li></ul><ul><li>Everything is there – you just need to make a good search. It’s a shortcut if teachers allow you to type out your homework, because you can copy and paste. </li></ul><ul><li>Internet provides the majority of information, if I want to find from other sources, it would take a longer time. </li></ul><ul><li>Although the book was available on the OPAC, I could not locate them on the shelves. </li></ul><ul><li>Honestly, during these 3 years in campus, I always go to the library, but seldom use the facilities. I just go inside and read my own book. There is not enough reference materials for me as an IT student. </li></ul>What the Malaysian students have to say… Source: Abdullah, A., & Zainab, A.N. (2007). Are Malaysian students ready to be authors of digital contents? A case study of digital library stakeholders' readiness. Journal of Educational Media & Library Sciences, 45(1), 55-73.

International Conference of Libraries, Information and Society (ICOLIS), 291-304.
    22. 22. Influence of the web <ul><li>OCLC survey - 84% respondents begin their search for information via internet vs 1% on library web site </li></ul><ul><li>Popularity of the web have influenced users' mental models </li></ul><ul><li>Online providers such as Amazon and Google have raised the bar for the delivery of information and expectations for library services </li></ul><ul><li>Users expect library catalogs to work as well as Amazon’s web site </li></ul><ul><li>Users expect to find as much relevant material through the library’s web page as they seem to find through Google </li></ul>
    23. 23. Challenges to libraries <ul><li>User less willing to work hard (unlike the older days) to make links/connections between resources since they have had the web </li></ul><ul><li>Library catalog has become a call-number lookup system, with resource discovery happening elsewhere </li></ul><ul><li>Does not mean that they are not interested in library services, but they may not discover those services if the library does not find a way to go to the user </li></ul><ul><li>If libraries are not able to follow the technological innovations and the trends on the web, libraries will not be able to compete and may lose their position as primary information providers </li></ul>
    24. 24. 5.0 What the users want
    25. 25. Information architecture is about… The art and science of structuring, organizing and labeling information to help people find and manage information
    26. 26. Understanding user needs and expectations <ul><li>Being able to reserve books online is the greatest!! </li></ul><ul><li>Make access to the online search engines much easier. </li></ul><ul><li>Much of the information I look for does not have enough of a description to really decide whether it is good information, especially if I have to do an interlibrary loan. </li></ul><ul><li>Advertise? I have forgotten about libraries since I left school. </li></ul><ul><li>Advertise a bit more; until this survey I didn’t really realize that a library might have music, movies and audio books to borrow. </li></ul><ul><li>Make a way to search through all of the databases with one search engine, instead of having to search each database individually. I despise searching the library for books and other sources. </li></ul>Source: De Rosa, C., Cantrell, J., Cellentani, D., Hawk, J., Henkins, L. & Wilson, A. (2005) Perceptions of Libraries and Information Resources: A Report to the OCLC Membership. OCLC Online Computer Library Center, Inc. Retrieved from What users have to say…
    27. 27. Understanding user needs and expectations <ul><li>I like the catalog, but if it could reference some sort of rating system it would be even better—I was looking at a new author today who has many books, and I had to go to an internet computer, check on Amazon and see which books were most highly recommended and go back to the catalog to see if they were available. </li></ul><ul><li>Please let us study there longer!!! </li></ul><ul><li>There is no toilet in my library so getting information must be quick. </li></ul><ul><li>E-mail reminders warning when books are due. </li></ul><ul><li>Run the library like a bookstore. </li></ul>Source: De Rosa, C., Cantrell, J., Cellentani, D., Hawk, J., Henkins, L. & Wilson, A. (2005) Perceptions of Libraries and Information Resources: A Report to the OCLC Membership. OCLC Online Computer Library Center, Inc. Retrieved from What users have to say…
    28. 28. What we learned from the users <ul><li>Quality and quantity of information are top determinants of a satisfactory information search. Search engines are rated higher than librarians. </li></ul><ul><li>The criterion selected by most information consumers to evaluate electronic resources is that the information is worthwhile . Free is a close second. Speed has less impact. Respondents do not trust purchased information more than free information. There is high expectation of free information . </li></ul><ul><li>Library users like to self-serve. Most respondents do not seek assistance when using library resources. </li></ul><ul><li>Information consumers use the library less and read less since they began using the internet. The majority of respondents anticipate their usage of libraries will be flat in the future . </li></ul>Source: De Rosa, C., Cantrell, J., Cellentani, D., Hawk, J., Henkins, L. & Wilson, A. (2005) Perceptions of Libraries and Information Resources: A Report to the OCLC Membership. OCLC Online Computer Library Center, Inc. Retrieved from
    29. 29. What we learned from the users <ul><li>Borrowing print books is the library service used most. </li></ul><ul><li>“ Books” is the library brand . There is no runner-up. </li></ul><ul><li>Most information consumers are not aware of , nor do they use, most libraries’ electronic information resources . </li></ul><ul><li>Be clean, bright, comfortable, warm and well-lit ; be staffed by friendly people ; have hours that fit their lifestyles; and advertise services . </li></ul><ul><li>Find ways to get material to people , rather than making them come to the library. </li></ul>Source: De Rosa, C., Cantrell, J., Cellentani, D., Hawk, J., Henkins, L. & Wilson, A. (2005) Perceptions of Libraries and Information Resources: A Report to the OCLC Membership. OCLC Online Computer Library Center, Inc. Retrieved from
    30. 30. 6.0 Features for the “next” generation library catalog
    31. 31. Features of the “next” generation <ul><li>Sort flexibility </li></ul><ul><li>Enrich content </li></ul><ul><li>Browsing by shelf </li></ul><ul><li>Browsing by faceted search </li></ul><ul><li>Embedded citation metadata </li></ul><ul><li>Federated search/consolidated search </li></ul><ul><li>Linking and support through document delivery </li></ul><ul><li>Relevance ranking of results </li></ul><ul><li>Stemming </li></ul><ul><li>Spell-checking </li></ul><ul><li>Spelling correction </li></ul><ul><li>Advanced Search </li></ul><ul><li>Simple Search </li></ul><ul><li>Live chat with a librarian </li></ul><ul><li>Allowing user to enrich the catalog </li></ul><ul><li>User personalisation </li></ul>
    32. 32. Sort flexibility
    33. 33. Enrich content – book cover
    34. 34. Enrich content – summary, TOC, abstracts, editors review
    35. 35. Browsing by shelf
    36. 36. Browsing by faceted search
    37. 37. Embedded citation metadata
    38. 38. Federated search / Consolidated search <ul><li>One portal for all library content </li></ul><ul><ul><li>Library and non-library catalog </li></ul></ul><ul><li>One-stop “shopping” centre for users </li></ul><ul><li>Less user training required </li></ul><ul><li>Enhance user information discovery </li></ul>Benefits of federated search
    39. 39. Linking and support through to document delivery
    40. 40. Relevance ranking of results
    41. 41. Stemming Entering &quot;swim&quot; might also find &quot;swims&quot; and &quot;swimming&quot;
    42. 42. Spell-checking Not because people do not know how to spell, but because people make mistakes
    43. 43. Spell correction, “Did you mean . . .”
    44. 44. Advanced search
    45. 45. Simple search Quick, Easy, Immediate Enter one or two words (or maybe a phrase) into a search box, click a button, get a list of relevancy ranks results returned, select an item from the results and view/download the information.
    46. 46. Live chat with a librarian Library of Congress answers questions and assists patrons with their research through online dialogue with patrons between 2 and 3 p.m., Monday through Friday
    47. 47. Allowing user to enrich the catalog <ul><li>Users add a comment to the record of a book they have borrowed. All this information may help another reader to know if the book they just identified will satisfy them. </li></ul><ul><li>Users add a rating usually represented by a maximum of 5 stars to the record of a book. </li></ul><ul><li>Users add a tag, a free keyword, to the record of a book. All these free tags constitute a folksonomy, a taxonomy built by non-professionals and that is not controlled. Those tags ameliorate the search function and help users to identify books of interest. This is also another feature for metadata enrichment. </li></ul><ul><li>When looking at a book's record, a user may get suggestions based on loans of users that have also borrowed the book. Library users may also discover books of interest thanks to the functions “suggested reading” or “people who borrowed this book also borrowed…”. </li></ul>Commenting Rating Tagging Book suggestion
    48. 48. Allowing user to enrich the catalog Book suggestion
    49. 49. User personalisation <ul><li>Other forms of personalisation include: </li></ul><ul><ul><li>register to be alerted of new table of contents </li></ul></ul><ul><ul><li>maintain a list of items checked-out </li></ul></ul><ul><ul><li>maintain a list of items ever borrowed </li></ul></ul><ul><ul><li>choose interface design and needed tools </li></ul></ul>
    50. 50. 7.0 Three questions regarding information architecture
    51. 51. Information architecture is about… The art and science of structuring, organizing and labeling information to help people find and manage information
    52. 52. Understand your users <ul><li>Define the primary audience of your information system - university's students, faculty and staff </li></ul><ul><ul><li>needs of these people take precedence over the needs of the general public, alumni or scholars from other institutions </li></ul></ul><ul><ul><li>limited resources and it is not possible to be all things to all people at all times </li></ul></ul><ul><li>Learn what they need and desire - build relationships with them </li></ul><ul><ul><li>surveys, information interviews, focus group interviews, usability studies and transactions log analysis </li></ul></ul><ul><ul><li>understand the challenges and difficulties they are having when it comes to doing their work </li></ul></ul><ul><ul><li>learn their priorities </li></ul></ul>
    53. 53. Understand your users <ul><li>Why it is important to understand your users? </li></ul><ul><ul><li>A survey found that while users showed interest in OPAC Web 2.0 functionalities, they are still “Users 1.0” </li></ul></ul><ul><ul><li>They surf regularly and use information from the web </li></ul></ul><ul><ul><li>Best known are comments and suggestions. Tagging and rating are less known </li></ul></ul><ul><ul><li>But even if the functionality is known, it is rarely used </li></ul></ul>Source: Chalon, P., Di Pretoro, E., & Kohn, L. (2008). OPAC 2.0: Opportunities, development and analysis. European Association for Health Information and Libraries (EAHIL) 11th Conference.
    54. 54. Know your business context <ul><li>Understanding your organisation’s objectives, politics, culture, technology, resources and constraints </li></ul><ul><li>Know the purpose, goals and priorities of your institution </li></ul><ul><li>Look to your institution's vision and mission statement for answers </li></ul><ul><li>What problems is it trying to solve? </li></ul><ul><li>How can your information system be expected to contribute to the solutions? </li></ul>
    55. 55. Know your business context <ul><li>Why it is important to know your business context? </li></ul><ul><ul><li>There is no such thing as unlimited amount of resources </li></ul></ul><ul><ul><li>These resources can take the form of time, money, hardware, software, people and expertise </li></ul></ul><ul><ul><li>Implementation and ongoing maintenance of your information system will require a diverse set of skills </li></ul></ul><ul><ul><li>The people with the necessary skills include subject experts, leaders of people, graphic designers, people who can mark up texts, knowledge workers who can organise content, usability experts, marketers, programmers and systems administrators </li></ul></ul><ul><ul><li>None of which are necessarily more important than the other </li></ul></ul>
    56. 56. Create relevant content <ul><li>Define your library’s collection development policy </li></ul><ul><li>Focus on the answers regarding users and context to define the scope of your content </li></ul><ul><li>What are the strengths of my institution? </li></ul><ul><li>To what degree does my collection need to be comprehensive, authoritative, up-to-date, written in a particular language, presented in an aesthetically pleasing manner, etc? </li></ul>
    57. 57. Create relevant content <ul><li>Why is defining your library’s collection development policy important? </li></ul><ul><ul><li>Again, it falls back to the answer that resources are limited </li></ul></ul><ul><ul><li>Not even Google provides access to the totality of the world's content, and there is no reason to expect you to fill this role </li></ul></ul><ul><li>Create a list of guidelines that your information resources need to embody in order to be a part of your collection </li></ul><ul><li>Just because a particular information resource is about a particular subject does not necessarily mean it is a good candidate </li></ul>
    58. 58. 8.0 Conclusion
    59. 59. The long and arduous journey… <ul><li>Some changes will improve a library’s standing in the community </li></ul><ul><li>Some may bring in new audiences </li></ul><ul><li>Some will go unused and if tracked properly may be abandoned </li></ul><ul><li>Some of those changes may be viewed as disruptive </li></ul><ul><li>Some just will not be feasible for some libraries </li></ul><ul><li>Some of those patrons will love some of the new services that come under the Library 2.0 rubric, as long as they do not detract from the successful old services and collections </li></ul><ul><li>Some simply will no use them; that is all right, as long as the new services do not displace or weaken successful existing services </li></ul><ul><li>Some of the tools and concepts can be used with little or no monetary investment and expertise </li></ul><ul><li>Some of them will not work out for you; some will </li></ul>
    60. 60. Do not try to do it all <ul><li>Do not worry about doing it all—you cannot. </li></ul><ul><li>Consider the benefits of each change, but do not assume that all change is inherently good </li></ul><ul><li>This way, you will probably build a better library and enjoy your work more in the process </li></ul><ul><li>  Finally, do not worry too much about “Library 2.0” or “OPAC 2.0” or “Web 2.0” - they are just names </li></ul><ul><li>Deep in our hearts, we know that Metadata and Library Catalog will never ever be a finished, perfected product! </li></ul>
