  1. New technologies in the libraries Stu Baker Library Management Systems stubaker@northwestern.edu Northwestern University Library

  2. Overview • Problems being solved • SFX (Open URL Linking) • MetaLib (Federated Search) • EZproxy (Remote Access) • Next steps • Questions

  3. The problems at hand • Growth of library’s electronic resources • Approximately 32,000 electronic resources • Electronic resources expenditures $3.2 million • 38.0% of our total collection budget • Patrons need to find known items (SFX) • Discover appropriate resources (Metalib) • Seamless remote access (EZproxy)

  4. What we were doing • NUcat - online library catalog • ER (Electronic Resources) database • Remote access • Proxy Server • Proxy CGI • VPN Client

  5. What we will be doing • NUcat - online library catalog • SFX - item level article access • MetaLib - federated search interface • EZproxy and VPN - remote access

  6. FirstSearch EBSCO What does SFX do? OpenURL resolver

  7. How does SFX do that? • Through OpenURL • A standard means for identifying content • Provides a mechanism for encoding a citation for an information resource, typically a bibliographic resource, as a URI • URL • DOI

  8. What can it link from and to? • OPAC (online public access catalog) • Abstract/index databases • Full-text databases • OpenURL-enabled resources • Citations • Table of contents • Web forms • Repositories

  9. http://hopper.library.northwestern.edu/sfx?genre=article &issn=0100-0293&volume=32&issue=1&spage=55& epage=76&date=2003&aulast=Gergenplotz&aufirst=Joe How does this work? OpenURL resolver • Redirection through a resolver • Resolver interprets data • Digital Object Identifier (DOI) • A URL encoded with metadata about the resource • Locates appropriate copies • Displays choices Citation metadata

  10. The schematic diagram Dynamically generates an appropriate target list The OpenURL resolver analyzes the URL Target Link source (citation) OpenURL resolver Target Open URL Target Source sends OpenURL info to local OpenURL resolver OpenURL resolver looks up holdings data in its internal database

  11. Let’s take a look…

  12. SFX Screen Logic • FindIt@NU will always display in active sources • The service menu will always appear if FindIt@NU button is clicked • Answers Online will always display • Downloading to RefWorks and EndNote will always appear as an option

  13. Three screen types • When full text is available • When a print copy is available • When Interlibrary loan is the only option

  14. But… • As nice as SFX is, it is just a stop on the destination to federated searching

  15. I think that an abstract of that article on usability testing in Tonga was in Expanded Academic but there was no full text! I need to finish my research today!I wonder if I can get the full text somewhere? The world of electronic resources Known database OpenURL resolver Link resolution

  16. FirstSearch EBSCO ProQuest Kluwer Federated search answers a different type of question I can never remember where the best place is to find articles on usability I know, I’ll use that new metasearch product we just installed Federatedsearchproduct Merged results list

  17. Where can I find information on that usability testing research in Tonga? If I could find those articles, my research would be complete! The world of electronic resources Federated searchengine OpenURLresolution Federated searching interface Link resolution

  18. EZproxy (remote access) • Vendor provided solution • Replacing Proxy Server and Proxy CGI • Using LDAP for identity management • Using “nuSchoolAffiliations” to determine appropriate access vs. IP address • SFX and MetaLib automatically route through EZproxy if needed.

  19. Summary • SFX provides the article resolution engine • MetaLib provides the interface and engine for federated searching • EZproxy is replacing existing proxy servers • Works with SFX and MetaLib to provide seamless off-campus access

  20. Next Steps • SFX in production and is available through target resources • EZproxy is in production and is invoked when needed by applications. • MetaLib coming soon, links on library home page and ER sites • Enhanced versions of SFX/MetaLib by Winter quarter • ER phased out by next summer
