- Abstract
- Myriad new information resources are available to contemporary library users. While print remains the foundation of most collections, libraries are also beginning to provide access to an array of bibliographic, numeric, and full-text databases. As more and more information is produced in electronic form and presented at computer workstations, the library catalog is being given an expanded role. The expanded catalog will play a crucial part in organizing information in electronic libraries, and in providing navigational assistance to library users. Like the traditional card catalog, the expanded catalog will not only lead to specific items or groups of sources, but also will provide connections to related materials. These connections will uses standard data elements to link the results of a search in one database with related material in another. For example, links will show local library holdings of sources in citation databases. Cornell University's Mann Library serves the College of Agriculture and Life Sciences, the College of Human Ecology, and the Division of Biological Sciences. As part of electronic library development, Mann staff have been analyzing issues involved in making it possible for Agricola and BIOSIS users to see, automatically, which of their retrieved citations are from sources available in the Cornell libraries. Samples of citations from Agricola and BIOSIS were drawn, and data elements present in these records were compared with bibliographic records of the library's holdings. In some cases, links would be provided by ISSNs. The study shows, however, that the presence of standard identifiers such as ISSN, USBN, or CODEN cannot be assumed, and other linking algorithms must be developed. This article presents study results, provides an overview of several linking systems, and identifies some of the difficulties caused by lack of standardization between different bibliographic databases. It is clear that the concept of an expanded catalog will require not only links between information resources but agreements among information professionals on standard data elements.

- Abstract
- Analysis of research to date on improving subject access by including contents tables in bibliographic records. Results indicate the need for clear methodology (criteria for selecting notoces for enrichment, manual and semi automated methods, cost). Evaluations, based on recall, precision and rate of circulation, indicate manifest benefits, especially in virtual libraries where information is superabundant; but enrichment is a complex process

- 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
- In 1986, all titles added to the collection at the Australian Defence Force Academy Library, are processed through their OPAC via a subject enhancement procedure (ESP). The procedure used for subject enhancement is based on the techniques developed by P.A. Atherton and B. Settel during the Subject Access Project at Syracuse Univ., 1977. Terms are selected from contents pages or the index of the book, depending on whether the terms are content bearing, and whether the terms refer to 5 or more pages of text. This results in the addition of an average of 73 words or 20 phrases to each MARC record. The terms are keyed into the MARC field 653 using in house modifications of the library's URICA system

- 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

- Abstract
- Subject access plays an important part when plans are made for an on-line public access catalogue (OPAC). Therefore, current subject searching facilities in OPACs should be accessed carefully. These facilities include, amongst other things, phrase searching, keyword searching and class number retrieval. Users reaction have been instrumental in identifying certain shortcomings in subject access to OPACs. Points out certain shortcomings in subject access, as shown by a number of research projects undertaken during the past decade. Highlights aspects which could, in future, improve subject access in OPACs. This could be achieved by either enhancing content representation in the records within the OPAC data base or by enhancing the searchability and browsability of the OPAC. Considers whether the on-line catalogue will ever be a finished, perfect product, or achieve the universal, familiar uniformity experienced by users of the 20th century card catalogue.

- Abstract
- This paper reports on a project undertaken at the American Museum of Natural History Library in 1997 and intended to enhance access to materials in the library's collection by using scanning and OCR software to digitize and add monograph tables of contents to the OPAC bibliographic records. Initially, conference proceedings already in the collection were used, but, as the project developed, other types of materials were also used. The rationale for the project is explained, the procedure developed is described, and the lessons learned from using this particular technology are outlined.
