Abstract

When an item catalogued in a library's bibliographic database consists of more than a sole work, it may be difficult to link the works to the item. For the retrieval of such works, online catalogues currently rely on contents notes and added entry fields. Suggests 4 criteria for analytic catalogues: a search for a specific work should retrieve all units of that work; it should retrieve only that work without false drops; the search should require only one pass; and the resulting display should clearly collocate all retrieved works. Suggests that 'In' analytics as described in AACR2 rule 13.5A promise better results than analytic entries based on contents notes and added entries

Abstract

At present cataloguing of Internet resources are on 2 levels. At level 1, the description of resources is contained in local library catalogues, along with bibliographic surrogates for all other materials that the library access, based on AACR2/MARC systems. At level 2, Internet resources are organized independently of any library agency. These include separate catalogues of selected resources, subject browsing lists and robot-generated search tools, and focus exclusively on Internet resources. A 3rd level needs to be developed - a metacatalogue - whereby a user can identify specific library catalogues to include in a search query of other Internet databases

Abstract

The Functional Requirements for Bibliographic Records (FRBR)'s hierarchical system defines families of bibliographic relationship between records and collocates them better than most extant bibliographic systems. Certain library materials (especially audio-visual formats) pose notable challenges to search and retrieval; the first benefits of a FRBRized system would be felt in music libraries, but research already has proven its advantages for fine arts, theology, and literature-the bulk of the non-science, technology, and mathematics collections. This report will summarize the benefits of FRBR to next-generation library catalogs and OPACs, and will review the handful of ILS and catalog systems currently operating with its theoretical structure.

Abstract

This paper presents the first large-scale investigation of the users and uses of WorldCat.org, the world's largest bibliographic database and global union catalog. Using a mixed-methods approach involving focus group interviews with 120 participants, an online survey with 2,918 responses, and an analysis of transaction logs of approximately 15 million sessions from WorldCat.org, the study provides a new understanding of the context for global union catalog use. We find that WorldCat.org is accessed by a diverse population, with the three primary user groups being librarians, students, and academics. Use of the system is found to fall within three broad types of work-task (professional, academic, and leisure), and we also present an emergent taxonomy of search tasks that encompass known-item, unknown-item, and institutional information searches. Our results support the notion that union catalogs are primarily used for known-item searches, although the volume of traffic to WorldCat.org means that unknown-item searches nonetheless represent an estimated 250,000 sessions per month. Search engine referrals account for almost half of all traffic, but although WorldCat.org effectively connects users referred from institutional library catalogs to other libraries holding a sought item, users arriving from a search engine are less likely to connect to a library.

Abstract

Duplicate records is a familiar problem in bibliographic databases. The problem is obvious when a union catalogue is established by automatically merging two or more separate and independent source of catalogue information. However, even in systems with on-line cataloguing and access to previous records, duplication is a problem. Author / title search search prior to cataloguing does not cut duplication to zero. A great deal of effort has been put into developing methods of duplicate detection. A major problem in this work has been efficiency. Particularly in the on-line setting is this of importance. Most studies have dealt with book and article material. The Research Libraries Group Inc. has described matching algorithms also for films, maps, recordings, scores and serials. Various methods of detecting duplicates will be discussed.

Abstract

Looks at access problems that occur when the citations from indexes for articles in series differ from the way the items are catalogued. To illustrate the difficulties encountered,a search was conducted in the online catalogues of various libraries and a comparison made between the bibliographiuc entries found to citations both in electronic indexes and in authors' references. The series: New directions for community colleges (NDCC); was chosen as it has kept the same title, ISSN and editors since 1973; yet is still illusive to identify. Each issue of NDCC, beginning with issue 1, 1973, was examined for citation information, numbering systems and changes in description on the title page. The online catalogue at Ohio State University (OSCAR) was checked to see how each issue was handled over time. Indexes consulted included: ERIC, Education Index; ArticleFirst; and CARL UnCover. Results indicate that the ramifications of local cataloguing decisions affect all areas of librarianship. In this electronic age, the need is great to integrate the various sources of information needed for a patron to go from citation to piece in hand

Abstract

Effective resourcesharing presupposes an infrastructure which permits users to locate materials of interest in both print and electronic formats. 2 approaches for providing this are union catalogues and Z39.50 based distributed search systems and computer to computer information retrieval protocols. The advantages and limitations of each approach are considered, paying particular attention to a relaistic assessment of Z39.50 implementations. Argues that the union catalogue is far from obsolete and the 2 approaches should be considered complementary rather than competitive. Technologies to create links between the bibliographic apparatus of catalogues and abstracting and indexing databases and primary content in electronic form, such as the new Serial Item and Contribution Identifier (SICI) standard are also discussed as key elements in the infrastructure to support resource sharing

Abstract

Evaluates OCLC's InterCAT, a WWW site which aims to catalogue the Internet. Cooperating libraries catalogue items on the Internet, and provide MARC records for them. These are available on the WWW as a searchable database. The MARC field 856 provides electronic access to the material catalogued. Discovers problems with locating resources from search results, because of the cataloguing rules used to create the records and determine the references

Abstract

Reports on a study which aimed to determine the extent to which cataloguing can be reduced when cataloguing a book for a single screen minicat results from a search using the surname of the author of the book. The results show that the percentage of books having personal authors that are catalogued in a research library that will become entries in a 1 screen minicat is 35.6 when searched. Library could significantly reduce cataloguing expenditures by simplifying cataloguing nearly 2/5s of the time

Abstract

The pressures towards downsizing and outsourcing in cataloguing departments may reduce access to bibliographic and other information. Outsourcing could result in the inability to catalogue useful materials locally and integrate new cataloguing into the existing cataloguing. Sharing catalogues with other libraries creates problems with authority control. Catalogues will become increasingly unpredictable and unreliable as a search tool

Abstract

Use of dynamic links from subject-based finding aids to records for electronic resources in the OPAC is suggested as one method for by-passing the OPAC search interface, thus making the library's electronic resources more accessible. This method simplifies maintenance of links to electronic resources and aids instruction by providing a single, consistent access point to them. Results of a usage study from before and after this project was completed show a consistent, often dramatic increase in use of the library's electronic resources.
