  1. From Seamless to Limitless Access David Stern Director of Science Libraries and Information Services Yale University david.e.stern@yale.edu New York, May 8 2003

  2. Industry Trends Searching Issues • Keywords • Controlled vocabulary • Citation tracking • Cross-database searching Linking issues • DOI-based links (CrossRef) • “appropriate copy problem” • local resolvers (sfx) • Metadata-driven (enhanced) links

  3. Standard Search/Link Model SEARCHER INDEX LINK FULL-TEXT

  4. Enhanced Search/Link Model Database1 Database2 Database3 SEARCHER INDEX LINK FULL-TEXT Sound Images Datasets WWW search engines Citation searches Biographies Reviews METADATA re-search

  5. Enhanced options • Searching • Broadcast and Federated • Multiple simultaneous databases • On-demand outreach to targets • Harvesting (pre-createdcentral index) • Standard syntax conversion(s) • Limits by discipline/material type • Integrated • Media type (metadata) • Normalized indexing • vocabularies • hierarchies

  6. Enhanced options II • Linking • Standard concerns • Multiple resources (html, pdf) • Local resolvers (subscriptions) • Local subscriptions (aggregators) • Customized link “brand” (logo) • Enhanced possibilities • Customized to local options • Local resources • Selected added-value tools • Metadata re-searching • Obtain additional descriptors • Search across additional engines

  7. Paradox introduced and solved • Problem • Information overload • Solution • Additional sources searched WITH • Single search syntax • Immediate limit options before search • Navigation assistance • Local resources identified/linked • Relevant resources highlighted • Enhanced metadata re-searching • Obtain additional logical relationships

  8. Example broadcast and federated systems • MetaLib (Boston College) • Flashpoint (Los Alamos) • Multi-SEARCH (U Arizona) • SearchLight (CDL) • OAI (many initiatives) • CogPrints • Dspace • Eprints • OAIster (Michigan)

  9. Example linking systems • ResearchIndex (sophisticated links) • Citebase (ranking) • ARC (eprint archives) • http://www.library.yale.edu/~dstern/advancedsearch.html
