- Abstract
- This paper suggests that the cataloging community may be setting its goals too low in its approach to online subject access. Truly effective subject retrieval for online catalog users will not be possible until the Library of Congress gives a higher priority to consistency in the assignment of subject headings. In recognition of the intellectual complexity of LCSH, the paper proposes the appointment of subject specialists to monitor the assignment of subject headings at the Library of Congress.

- Abstract
- The growth and use of aggregator databases have presented libraries with both new opportunities for collection enhancement and new challenges of bibliographic control. How to integrate full-text electronic journal titles in unstable aggregator databases into a library's OPAC (Online Public Access Catalog) has been an especially taxing matter for libraries. This article describes the Hong Kong Baptist University Library's effort to integrate full-text electronic journal titles from three large, unstable aggregator databases into its INNOPAC-based OPAC. The library's electronic journal computer program (EJCOP) does this in a simple, direct, consistent, and accurate manner and addresses some of the issues elaborated in the January 2000 Final Report of the Task Group on Journals in Aggregator Databases of the Standing Committee on Automation of the Library of Congress Program for Cooperative Cataloging.

- Abstract
- In this article, we examine some of the proposals which have dealt with the problems in cataloging in 2 different technological contexts: printed-card catalogs and online catalogs. We first look at some of the measures which attempted to deal with the 'crisis in cataloging' at the Library of Congress in the 1940s. Then we address some of the current problems in cataloging in the era of OPACs. In particular, we discuss the extent to which minimal-level cataloging, as defines by AACR and implemented in the OCLC database, works for maps. Our discussion is organized around 2 main groups of access points: controlled vocabulary data elements, including name data elements, and free-text data elements. In closing, we discuss prospects that the next generation of online catalogs uisng the Z39.50 protocol and SGML format might offer to minimal-level cataloging for maps

- Abstract
- This short guide is intended to help librarians and OPAC system designers to make decisions about the design of displays of more than one subject heading. The authors stress that they offer guidance rather than standards or prescriptions; their clear prose is cautious and even the number of recommendations is limited. A 12-page introduction contrasts the "structural approach" and "strict alphabetical approach" to filing, showing examples and stating arguments for each. 7 chapters cover display of subdivisions, inverted headings, display of qualified headings, arrangement of numerical headings, display of subjects interfiled with names and titles, punctuation and messages to the user. Within each chapter, questions involving choices between two or more approaches are followed by brief statements of current practice (LC rules, ALA rules, and systems in existing OPACs) extensive examples demonstrating such choices, and arguments for and against each. The authors warn against ever assuming that the user knows the needed subject headings, and acknowledge that the best OPAC design often depends on the setting and on the user's understanding of the system. Although the topic may be beyond the purview of the authoring committee, the discussion here makes one yearn for interactive OPACs that can analyze the user's needs and provide appropriate guidance to whatever system is adopted

- Abstract
- According to the Calhoun report, library operations that are not digital, that do not result in resources that are remotely accessible, that involve professional human judgement or expertise, or that require conceptual categorization and standardization rather than relevance ranking of keywords, do not fit into its proposed "leadership" strategy. This strategy itself, however, is based on an inappropriate business model - and a misrepresentation of that business model to begin with. The Calhoun report draws unjustified conclusions about the digital age, inflates wishful thinking, fails to make critical distinctions, and disregards (as well as mischaracterizes) an alternative "niche" strategy for research libraries, to promote scholarship (rather than increase "market position"). Its recommendations to eliminate Library of Congress Subject Headings, and to use "fast turnaround" time as the "gold standard" in cataloging, are particularly unjustified, and would have serious negative consequences for the capacity of research libraries to promote scholarly research.

- Abstract
- Library OPACs have long been the gateways between users and information. They present to users the achievements of library automation, and are the most widely available automated retrieval systems and the first that many user encounter. Current trends in OPAC design are toward a user oriented, individual information service which can meet the different needs of users with a variety of background and interests. Compared with the rather inactive, short term and general information service of conventional systems, this type of system focuses on active, long term and personalized service. Proposes a framework for the design of such an OPAC and discusses some recent developments in personalized information service

- Abstract
- This think piece tells why the online library catalog fell from grace and why new directions pertaining to cataloging simplification and primary sources will not attract people back to the online catalog. It proposes an alternative direction that has greater likelihood of regaining the online catalog's lofty status and longtime users. Such a direction will require paradigm shifts in library cataloging and in the design and development of online library catalogs that heed catalog users' longtime demands for improvements to the searching experience. Our failure to respond accordingly may permanently exile scholarly and scientific information to a netherworld where no one searches while less reliable, accurate, and objective sources of information thrive in a paradise where people prefer to search for information.
The impetus for this essay is the library community's uncertainty regarding the present and future direction of the library catalog in the era of Google and mass digitization projects. The uncertainty is evident at the highest levels. Deanna Marcum, Associate Librarian for Library Services at the Library of Congress (LC), is struck by undergraduate students who favor digital resources over the online library catalog because such resources are available at anytime and from anywhere (Marcum, 2006). She suggests that "the detailed attention that we have been paying to descriptive cataloging may no longer be justified ... retooled catalogers could give more time to authority control, subject analysis, [and] resource identification and evaluation" (Marcum, 2006, 8). In an abrupt about-face, LC terminated series added entries in cataloging records, one of the few subject-rich fields in such records (Cataloging Policy and Support Office, 2006). Mann (2006b) and Schniderman (2006) cite evidence of LC's prevailing viewpoint in favor of simplifying cataloging at the expense of subject cataloging. LC commissioned Karen Calhoun (2006) to prepare a report on "revitalizing" the online library catalog. Calhoun's directive is clear: divert resources from cataloging mass-produced formats (e.g., books) to cataloging the unique primary sources (e.g., archives, special collections, teaching objects, research by-products). She sums up her rationale for such a directive, "The existing local catalog's market position has eroded to the point where there is real concern for its ability to weather the competition for information seekers' attention" (p. 10). At the University of California Libraries (2005), a task force's recommendations parallel those in Calhoun report especially regarding the elimination of subject headings in favor of automatically generated metadata. Contemplating these events prompted me to revisit the glorious past of the online library catalog. For a decade and a half beginning in the early 1980s, the online library catalog was the jewel in the crown when people eagerly queued at its terminals to find information written by the world's experts. I despair how eagerly people now embrace Google because of the suspect provenance of the information Google retrieves. Long ago, we could have added more value to the online library catalog but the only thing we changed was the catalog's medium. Our failure to act back then cost the online catalog the crown. Now that the era of mass digitization has begun, we have a second chance at redesigning the online library catalog, getting it right, coaxing back old users, and attracting new ones. Let's revisit the past, reconsidering missed opportunities, reassessing their merits, combining them with new directions, making bold decisions and acting decisively on them.

- Abstract
- In Northern Germany, the State of Lower Saxony has developed an online library network, the center of which is the Library Computer Center at the State and University Library in Goettingen. This center offers the following data bases online: the union catalogue of serials in Lower Saxony libraries; the union catalogue of books since 1977 in these libraries; the IBZ and IBR; the last two years of the Deutsche Bibliographie, the British National Bibliography and, within the next few months, the titles offered by the Library of Congress (all in full service); then all new titles in this data base will be compatible to MARC II.

- Abstract
- Central to subject searching is the match between user vocabulary and the headings from Library of Congress Subject-Headings (LCSH) used in a library catalog. This paper evaluates previous matching studies, proposes a detailed list of matching categories, and tests LCSH in a study using these categories. Exact and partial match categories are defined for single LCSH and multiple LCSH matches to user expressions. One no-match category is included. Transaction logs from ORION, UCLA's online Information system, were used to collect user expressions for a comparison of LCSH and user language. Results show that single LCSH headings match user expressions exactly about 47% of the time; that single subject heading matches, including exact matches, comprise 74% of the total; that partial matches, to both single and multiple headings, comprise about 21% of the total; and that no match occurs 5% of the time.

- Abstract
- The main purpose of the study was to determine if the online catalog can function both as a dictionary and classified catalog without requiring additional time or intellectual effort on the part of the cataloger. A total of 1842 MARC bibliographic records listed in the 370-379 classified section of American Book Publishing Record were studied. These records displayed 2735 subject headings. Of these, 1491 (55%) had a Library of Congress classification number linked to them. An alphabetical and classified index was created using primary subjects and their related classification numbers. While such an index could be a useful browsing device if integrated into an online catalog, creating a bona fide classified catalog would require assigning classification numbers to the secondary subject headings.

- Abstract
- Documents in digital and paper libraries may be arranged, based on their topics, in order to facilitate browsing. It may seem intuitively obvious that ordering documents by their subject should improve browsing performance; the results presented in this article suggest that ordering library materials by their Gray code values and through using links consistent with the small world model of document relationships is consistent with improving browsing performance. Below, library circulation data, including ordering with Library of Congress Classification numbers and Library of Congress Subject Headings, are used to provide information useful in generating user-centered document arrangements, as well as user-independent arrangements. Documents may be linearly arranged so they can be placed in a line by topic, such as on a library shelf, or in a list on a computer display. Crossover links, jumps between a document and another document to which it is not adjacent, can be used in library databases to allow additional paths that one might take when browsing. The improvement that is obtained with different combinations of document orderings and different crossovers is examined and applications suggested.

- This article first compares and contrasts the essential, fundamental differences between traditional and digital information mediums. It then reexamines the role of the online public access catalog (OPAC), refines the definition of library's catalog, and advocates the addition of Internet resources within the OPAC. Next, the article describes the building of the Alex Catalog, a catalog of Internet resources in the in the form of MARC records. Finally, this article outlines a process of integrating the futher inclusion of other Internet resources into OPACs as well as some of the obstacles such a process manifests.

- Abstract
- LIAS, the Pennsylvania State University's (Penn State) integrated interactive online system, provides for messaging by the user to inform library staff of errors found in bibliographic records. The message is sent by use of the OOPS command, and results in a printout which is used by processing staff for online catalog maintenance. This article describes LIAS, the use of the OOPS command, the processing of the resulting OOPS reports, an assessment of the effect of its use, and some speculation on the expansion of the LIAS message system for use in catalog maintenance.

- Abstract
- The author presents the environment of the OPAC as a new revenue stream of high potential. He suggests that the abstracting and indexing community is neglecting this important source and suggests industry-wide adoption of open standards as a remedy

- Abstract
- Historically, library automation has focused attention on the automation of internal library processes, such as cataloging; however, a new generation of library automation systems intended for direct use by library patrons is emerging. These public-access computer systems are categorized and described. The types of public-access computer systems are: (1) catalog information systems, (2) electronic information systems, (3) information presentation systems, (4) instructional systems, (5) consultation systems, (6) information service and delivery systems, (7) conferencing systems, (8) integrative systems, and (9) end-user computing facilities. To be effective, these computer-based systems must be integrated with the traditional collections and services of libraries
