Abstract: Typographical errors in bibliographic records can cause retrieval problems in online catalogs. This study examined one hundred typographical errors in records in the OCLC WorldCat database. The local catalogs of five libraries holding the items described by the bibliographic records with typographical errors were searched to determine whether each library had corrected the errors. The study found that only 35.8 percent of the errors had been corrected. Knowledge of copy cataloging error rates can help underscore the importance of quality data in bibliographic utilities and, further, can serve as an indication to libraries whether they need to pay more attention to correcting types in the copy cataloging process.

Abstract: Catalogers at Harvard University have been adding form and genre data to MARC records in HOLLIS, the University's online library catalog, since 1994. The addition of this data in bibliographic records allows library users to more easily access some materials described in the catalog. This paper describes how form and genre data is indexed in the catalog and analyzes the value of adding, indexing, and using this bibliographic data.

Abstract

WWW sites, consisting mainly of links to other Internet resources, have begun to proliferate and these sites are valuable to library users and researchers because they bring together in a single Web site links to a comprehensive array of information resources. Because libraries may elect to include bibliographic records for these sites in their online catalogues, cataloguers should be aware of some of the main aspects of cataloguing this new type of resource. Concludes that cataloguers should be aware of the main types and different characteristics of these Web sites, how to describe them in bibliographic records and how to assign appropriate subject headings for them

Abstract

Typographical errors can block access to records in online catalogs; but, when a word contains a typo and is also spelled correctly elsewhere in the same record, access may not be blocked. To quantify the effect of typographical errors in records on information retrieval, we conducted a study to measure the proportion of records that contain a typographical error but that do not also contain a correct spelling of the same word. This article presents the experimental design, results of the study, and a statistical analysis of the results.We find that the average proportion of records that are blocked by the presence of a typo (that is, records in which a correct spelling of the word does not also occur) ranges from 35% to 99%, depending upon the frequency of the word being searched and the likelihood of the word being misspelled.

Abstract

Mbooks are open-access, digitized books freely available on the Internet. This article describes the Auraria Library's experience of loading brief MARC records for Mbooks into its online public access catalog and looks at some of the issues that arose from the record-loading project. Despite the low quality of the records, librarians in Auraria Library thought that loading them into the catalog was advantageous because of the rich content in the collection and because many of the records could be improved using the global update functionality in the catalog. Making the records available through the catalog, as opposed to merely linking to the entire collection from the Library's web page, was considered to be valuable because of the aggregation a catalog provides and because the Mbooks collection helped fill gaps in the Library's physical collections. As more open-access, digitized books become available, libraries will need to plan and manage how best to provide access to them.
