Open. URL and Linking in Libraries: Distributed AND REIntegrated Information Systems Eric Hellman Founder, President Openly Informatics , Inc. Bloomfield, New Jersey

Outline • What is Open. URL? • What is a Link Server? • Demo and Technology Discussion

What is Open. URL? ? ? Open. URL is an internet equivalent of the index card in the (paper-based) card catalog – Packages bibliographic data – Can be presented to internet services – NISO Standard

What is a Link-Server? ? ? A Link-Server is an internet equivalent of a help desk in the (paper-based) library – Present it with bibliographic data or a query – It helps you locate the best information in the library – Standards-based - many product options; – 1 Cate, SFX, Link. Finder. Plus, Article. Linker, Link. Source, Link. Solver… – now widely deployed >1, 000 libraries

An internet library is built by librarians using electronic resources from many vendors ISI Journal Publishers Pub. Med Full text DBs EBSCO A&I service OPAC Google Scholar

Some services offer links to a few resources ISI Journal Publishers Pub. Med Full text DBs EBSCO A&I service OPAC Google Scholar Us er

Other services offer links to different resources ISI Journal Publishers User Pub. Med Full text DBs EBSCO A&I service OPAC Google Scholar

Linking is inconsistent and hard to manage ISI Journal Publishers Pub. Med Full text DBs EBSCO A&I service OPAC Google Scholar

Users are confused • Who is EBSCO? • What is a DOI? • Why doesn't my bookmark work?

A link server introduces consistent and comprehensive linking throughout the library ISI Journal Publisher Full text DBs Pub. Med 1 Cate EBSCO A&I service OPAC Google Scholar

Users see a Library, not a bunch of databases and a linking brand ISI ingenta Journal Publishers EBSCO Full text DBs A&I service The Library 1 Cate OPAC Google Us er

How URL’s fail target • • User's library doesn't subscribe to target URL target authenticates by IP, user is off campus User's library gets target item in a full-text aggregation User's library has a locally hosted copy of target journal User's country has a nationally hosted copy of target journal target has moved its content without telling source target has become a porn site This is known as the "Appropriate Copy Problem" source Us er

The link server lets the library fix these problems and determine which copy is appropriate ISI Journal Publishers Library subscribes A ingenta Full text DBs A Pay per view $$$ EBSCO A&I service OPAC Google Us er
