Abstract

The Jack Brause Library at New York University (NYU) is a special library supporting the curriculum of NYU's Real Estate Institute. The Jack Brause Library (JBL) Real estate Periodical Index was established in 1990 and draws on the library's collection of over 140 real estate periodicals. Describes the conversion of the JBL Index from a 3x5 card index to an online resource. The database was originally created using Rbase for DOS but this quickly became obsolete and in 1993 was replaced with InMagic. In 1997 the JBL Index was made available on NYU's telnet catalogue, BobCat, and the Internet database catalogue, BobCatPlus. The transition of InMagic data to USMARC formatted records involved a 3-step process: data normalization; adding value; and data recording. The Index has been operational through telnet since May 1997 and installing it onto the Web became functional in Oct 1997

Abstract

It is assumed that the conceptual structure of bibliographic records is based on the knowledge of user needs. In applying the entity-relationship model to the library catalogue the authority file and bibliographic records can be viewed as attributes, and the links between records and elements as relationships. Outlines the bibliographic relationships of the UNIMARC format, the analysis of hierarchical relationships carried out by Goosens and Mazur-Rzesos, and the typology of bibliographic documents established by McCallum. Presents 7 types of relationships developed by Tillet and gives results of an empirical study carried out to establish the extent and features of bibliographic relationships in the computerized catalogue of the Library of Congress
