Abstract: This report describes an experiment in subject enhancement conducted at an academic research library. Subjects and contents notes were added to online catalog records for a group of previously uncirculated social science essay collections, and circulation was monitored over one academic year. A control group, plus a third group with added contents notes but no extra subjects, were also monitored. Results showed an improvement in recorded use for the subject-enhanced titles, but not for titles that only had added contents notes. The effects of browsing, keyword searching, and OPAC display are discussed

Abstract: State of the art review of enhancements in online catalogues over a 3 year period, taking for granted those features that are now standard and mainly discussing issues related to problem areas, in particular, subject access and user searching behaviour, as well as new developments that directly impinge on the catalogue's future: new interface developments and network access and resources

Abstract

Reports results of research into the feasibility of using OCR scanner technology to capture contents pages of collective monographs and to extract the bibliographic information of each individual work and process this using a standardized language, such as SGML, for tagging electronic documents. By this means, data can be used as electronic information or stored in OPACs, thus providing additional access points. Outlines a pilot system to test the initial hypotheses, show the feasibility of achieving the suggested goals and develop the tasks required for them to be carried out as automatically as possible

Abstract

As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology

Abstract

Experimental evidence suggests that enhancing the subject content of OPAC records can improve retrieval performance. This is based on the use of natural language index terms derived from the table of contents and back-of-the-book index of documents. The research reported here investigates the alternative approach of translating these natural language terms into controlled vocabulary. Subject queries were collected by interview at the catalogue, and indexing of the queries demonstrated the impressive ability of PRECIS, and to a lesser extent LCSH, to represent users' information needs. DDC performed poorly in this respect. The assumption was made that an index language adequately specific to represent users' queries should be adequate to represent document contents. Searches were carried out on three test databases, and both natural language and PRECIS enhancement of MARC records increased the number of relevant documents found, with PRECIS showing the better performance. However, with weak stemming the advantage of PRECIS was lost. Consideration must also be given to the potential advantages of controlled vocabulary, over and above basic retrieval performance measures
