    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
    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
    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
    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
    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
    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
    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 article reports the findings of a survey of heads of cataloging in Ohio public libraries. The survey focused on subject enhancements in automated catalogs. Results reveal that additional subject access points and more anaytical entries ranked as the most useful enhancements for patrons. These enhancements were seen as less useful for technical services staff.

    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.

    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
    Describes the Intelligent Literature Search Assistant (ILSA) which demonstrates the possibilities of a fully automated cataloguing workbench in an object orientated environment. Although developed with OPAC users in mind, it can be very useful to cataloguers in aiding both classification and subject heading access. Also describes work done at the University of Strathclyde in the area of machine learning and knowledge based systems, the Structured Information Management: Processing and Retrieval project (SIMPR). Advocates the use of uncontrolled vocabulary headings in conjunction with systems like ILSA, a layered approach rather than direct first point access, in order to make subject cataloguing easier and more relevant and the subject catalogue more useful to others

    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

    Abstract
    This article describes our efforts in supporting information retrieval from OCR degraded text. In particular, we report our approach to an automatic cataloging and searching contest for books in multiple languages. In this contest, 500 books in English, German, French, and Italian published during the 1770s to 1970s are scanned into images and OCRed to digital text. The goal is to use only automatic ways to extract information for sophisticated searching. We adopted the vector space retrieval model, an n-gram indexing method, and a special weighting scheme to tackle this problem. Although the performance by this approach is slightly inferior to the best approach, which is mainly based on regular expression match, one advantage of our approach is that it is less language dependent and less layout sensitive, thus is readily applicable to other languages and document collections. Problems of OCR text retrieval for some Asian languages are also discussed in this article, and solutions are suggested
