of Internet Resources: An AUTOCAT Discussion.
J. McRee (Mac) Elrod,
Director, Special Libraries Cataloguing, Inc., Victoria, British Columbia.
ABSTRACT. In October of 1999 there was a discussion on AUTOCAT (an e-list for cataloguers) of the advantages and disadvantages of classifying Internet resources catalogued locally, which grew to include a discussion of cataloguing electronic resources generally. This article reviews the background of applying bibliographic description techniques to electronic resources, and summarizes the AUTOCAT discussion. The exchange of opinion confirms that while some librarians see classification as primarily a method of assigning a shelf location for a physical item, many others see classification as a valid subject approach for all the materials either in the library’s collection or available to the library's patrons through the library catalogue.
catalog as barrier to retrieval. Part 1: Hyphens and ampersands in titles.
H. Bowman,School of Library,
Archive & Information Studies, University College London, England
Abstract. An Internet survey of 38 different OPAC systems, at eighty different libraries, was undertaken to investigate the effect on retrieval of the presence of the hyphen or the ampersand in titles. Title and Keyword searches were performed. In Title search, 22 of the systems treat the hyphen as equivalent to a space, while in Keyword the number is 16. The other systems treat it is various different ways (even including the equivalent of NOT), which means that results of searching multiple catalogs are very inconsistent. The ampersand may be ignored, treated as a special character, or treated as “and,” again with very inconsistent results. Various recommendations are made with a view to improving consistency of performance.
Enhancing Bibliographic Records with Tables. Of
Contents Derived from OCR Technologies at the American Museum of Natural History
Library. By Evan Pappas and Ann
Herendeen . .
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.

Sizes and Composition: Their Effect on Recall and
Precision in IR experiments with OPACs. By
Charlotte Wien, Department of Journalism, Odense University, Odense,
Abstract. This article discusses how samples of records for laboratory IR experiments on OPACs can be constructed so that results obtained from different experiments can be compared. The literature on laboratory IR experiments seems to indicate that the retrieval effectiveness (recall and precision) is affected by the way the samples of records for such experiments are generated. Especially the amount of records and the subject area coverage of the records seems to affect the retrieval effectiveness. This article contains suggestions for the construction of samples for laboratory IR experiments on OPACs and demonstrates that the retrieval effectiveness is affected by different sample size and composition.
Impact of Productivity and Quality of CJK Cataloging
--A Brief Comparison Between CJK 2nd Edition and 3rd Edition. By Jiajian Hu, Catalog Division, the Chicago Public Library, Chicago, IL.
TO THE EDITOR An
Interview with Elaine Svenonius
Abstract: This report compares the features of the 2nd and 3rd editions of OCLC’s CJK cataloging as implemented at the Chicago Public Library. The 3rd edition is faster for cataloging than the 2nd edition. Alternatively, the 2nd edition has other benefits including stability. Perspectives such as the quality of CJK cataloging between the 2nd and the 3rd edition are discussed also.
Keywords: OCLC CJK. Information delivery.Cataloging of East Asian publications—Computer program. OCLC CJK software evaluation. Productivity of CJK cataloging. Quality control of CJK cataloging.

In an interview with Dorothy McGarry, Elaine Svenonius discusses her many-faceted career. Topics include her research interests in subject and descriptive cataloging (Svenonius notes that it “takes some untangling of vocabulary and semantics to see that the traditional bifurcation separating subject and descriptive cataloging is artificial”); her teaching experience, especially her use of Andrew Osborn’s “active learning” seminar method; and her views about the development of information science and its relationship to librarianship.
