Just-case linking vs. Just-in-time-linking - the Library Without Walls experience

摘要

The Library Without Walls (LWW) project began integrating full text links into citation databases early 1997. A local SICI database was developed to link between locally available full-text and citations in local databases. These could be termed just-in-case links as they are a predetermined set of URLs which link to specific full-text materials. Linking to full-text journals at external sites was the next step. A methodology was used to anticipate the URL for citations which could link to external full-text. As more types of electronic material became available, the presentation of different types of links became possible. A new approach to allow for a broad array of linking types (between citations and full-text, between varying databases and local holdings, from one database to another, etc.), and to allow for more customized linking based on the needs of the incoming user, is now being developed. This poster will cover how LWW has created a hybrid of just-in-case links with just-in-time links (links based on type and location of materials and on user needs); the origin of just-in-time links (Special Effects by Herbert Van de Sompel -University of Ghent); how the system works as Los Alamos; and how LWW customers have reacted to the hybrid system.
