Times are changing
With the advent of commodity-priced, globally networked computers, the information environment has obviously changed.Slide3
SpecificallyThe availability of full-text indexing techniques have made “hand-crafted” metadata records less necessary
Content is increasingly “born digital” and accessible beyond one’s own walls
Storage costs have plummeted allowing everybody to access the collection locally Slide4
Librarianship: What’s & How’s
Collection – Done by bibliographers and can be supplemented through the use of databases
Preservation – Done by archivists, and is most challenging in the current environment
Organization – Done by cataloguers and can be supplemented by databases and XML
Re-distribution – Done by reference librarians and can use intelligent interfaces to indexesSlide5
Services against the index and texts
annotate • buy • cite • compare & contrast • count occurrence of idea • create flip book • create tag cloud • discuss • do morphology • elaborate • find more like this one • find similar & different • get • graph • highlight • map • print • rank • reformat • remove from my list • renew • save to my list • search content of • search my list • share • summarize • trace citation forward & backward • trace idea forward & backward • translateSlide6
More specific examplesCreate tag cloud – graphically compare & contrast texts
Create flip book – provide alternative ways to search & browse materials
Annotate and share – exploit the wisdom of the crowdsSlide7
Future
The catalogue will be less about inventory and ownership. Instead it will be more about access and usefulness.Slide8
Library communities
Libraries are always members of larger hosting communities. Learn how to take advantage of this fact and put searches against the catalogue into the user’s context.Slide9
Databases and indexes
Database and indexes are two sides of the same information retrieval coin. Databases are great for maintaining content. Indexes are great at search. Learn how to exploit the strengths of both to create powerful information systems.Slide10
They are all the same
“Next-generation” library catalogue systems have more things in common than differences. They all ingest content, index it, and provide services against the index.Slide11
Suggestions
Index everything: books, journals, images, etc.
Make sure your content is accessible to the Big Three
Consider adding open access content
Apply your “library eye” to incoming queries
Repurpose the system by exploiting Service-oriented architectures and REST-ful computing techniquesSlide12
Summary
There are enormous opportunities for librarianship requiring a shift in attitudes and skills as well as time spent investigating ways to exploit the current environment.
A rising tide floats all boats.
