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.

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?

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.

Martin Schrettinger. 1772-1851 Forget the mind of God! (or “Nature”). Use an arbitrary systematic arrangement. New name: “Library science” 1808 -- 201 years ago.

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?

Any word, name, document, or event
Any resource:Audio, Images, Texts, Numeric data, Objects, Virtual reality, Webpages
Any catalog: Archives, Libraries, Museums, TV, Publishers
Connect it with its context – and other resources.

The reference library is open from
9:00 a.m. to 5:00 p.m.
The “9 to 5” problem
Students are writing papers at home on laptops from
9:00 p.m. to 5:00 a.m.
What is wrong with this situation?
What can librarians do about it?

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 note-talking and transcription.

Building the functionality of a reference collection.
1. Context finder: Search support from text to reference works.
2. 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.

Save search path
Save link & notes as “stand-off” markup.
Save link & notes as embedded mark-up.

Cursor over a name highlights every mention of that name in the text.

Named entities are linked to specific resources or dynamic searches over relevant databases.

Named entities not detected automatically can be added manually.

Initially, named entities are linked to keyword searches at the appropriate name authorities and metadata services. Here we see a number of possible candidates for “Henry V”.

2. Context builder: Making, retaining notes / links to reference works.
3. Context provider: Enriching reference works by adding reverse links, e.g. place name gazetteer mentions where a place is mentioned in texts.

Paper-based reference collection: Codex determines structure and use.
Reversed in a digital environment: Metadata forms infrastructure.
Build a union index, so you know where too look! Little green lights!

Importance of inverting the relationship between the part and the whole:
-- Indexes are created by inversion -- Union indexes: Tell you which reference work mentions
your query, like the Science Citation Index. . . as in Google.
Use dynamic links to for real time searches the latest version of the best resources; and, for vocabulary:Search term recommender systems.
