Access to Reference Resources In a Digital Environment Michael Buckland University of California, Berkeley Electronic Cultural Atlas Initiative School of Information SLIS, University of South Florida Tampa, February 3, 2009 USF, Feb 3, 2009 Reference resources 1 Some ideas about learning. . . . 1. Understanding requires knowing the context. “Knowledge is power” (Sir Francis Bacon) implies understanding relationships. 2. So libraries should support finding the context of anything! What? Where? When? Who? Whatever! 3. Best place to read is in a library among reference works. 4. The reference library has been largely forgotten in the move of library services into an online environment. 5. Using reference resources online should be as easy as Google and the Wikipedia to use and but also as reliable as a library reference collection. USF, Feb 3, 2009 Reference resources 2 In a paper environment, reading inside a library is the best place to learn. It is well designed to explain the context! How do we move this situation into an internet environment? Text Library resources with a interesting details. Who was she? Where is that? What is this? What else was happening? Encyclopedias Atlases, place name Biographical dictionaries Bibliographies Library catalog Statistical series etc., etc. . . . . USF, Feb 3, 2009 Reader Reference resources 3 Present situation – 1 -- Definition: “For the purpose of the research agenda, digital reference is defined . . . as the use of human intermediaries to answer questions in a digital environment.” Empowerment of librarians is good, but library science is really about designing services that empower library users, an even higher goal.

(or “Nature”). Use an arbitrary systematic arrangement. New name: “Library science” 1808 -- 201 years ago. USF, Feb 3, 2009 Reference resources 5 Present situation – 2: Stage of technology change. Adoption of new technology typically in two stages: First – Stage 1 - use new technology to do the same thing better. Second - Stage 2 - exploit the full capability of the new technology to do different better things. The Internet Public Library reference department is a good example of Stage 1, Time now for Stage 2! What would it look like? USF, Feb 3, 2009 Reference resources 6 Emanuel Goldberg, b.

What can librarians do about it? USF, Feb 3, 2009 Reference resources 11 And other problems with the paper reference collection . . . -- Designed for community, not for an individual. -- Designed for many queries, not the current one. -- Not volatile. -- Guides but no index. One doesn’t really know where to look. Little green lights on shelves indicating which volumes mention this topic would be nice. -- Multimedia in theory; bound volumes in practice. -- Disconnect with work practices: Much error-prone notetalking and transcription.

Context builder: Make, retain notes and links to reference works. 3. Context provider: Make reference works better by adding two-way links, e.g. text has links to place name list AND place name list has links to texts.

Use dynamic links to for real time searches the latest version of the best resources; and, for vocabulary: Search term recommender systems.
