- Abstract
- Subject access to monographs through online public access catalogs (OPACs) has always been a major concern for large research and/or academic libraries. Academic library practice of providing subject access to monographs has proven inadequate, especially in the case of composite works. Many techniques have been proposed to enhance subject treatment of monographs in OPACs. This article briefly reviews these efforts in the past and presents the case of adding Tables of Contents as one of the Most useful and probably also one of the Most costeffective ways of improving subject access to Monographs in an academic environment.

- 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
- 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
- From a logical point of view, an OPAC is an inventory with indexes. Inventories can be accumulated and the indexes merged. However, in most merged catalogues not all documents have the same subject indexing and a number of documents are indexed by more than one system. In practice, a merged catalogue also contains descriptions without subject indexing. To augment the situation four methods are used: searching with title keywords, mapping and switching, acceptance of descriptions indexed in a given way only, and »citation pearl growing«. The last method uses all available subject indicators by using subject indicators present in relevant descriptions found by already known indicators. This method can also be of help in mapping and switching.

- Abstract
- Traditional subject cataloguing hampers subject retrieval in central catalogues, because of the lack of a common indexing and retrieval language in these catalogues. This study investigates the possibilities to use the various individual subject access systems, present in the catalogues, for subject access. A search procedure based on 'citation pearl growing' and 'user relevance feedback', which can be applied in a public access interface to central data bases, has been developed. From an experiment it can be concluded, that automated expert assistance, provided with a search strategy, will improve search response for unexperienced searchers. It reduces the number of zero-hits and increases the number of relevant items retrieved
