Abstract: One of the most common errors in cataloguing library materials involves miscoding of the nonfiling indicator of title fields. Notes the extent of the problem and its negative effect on searching in the library's online catalogue and surveys how librarians have approached solutions to the problems. Describes how the major library automation system address this problem

Abstract: Offers a third alternative to the debate over subject vs. keyword searching in libraries. Provides a background of this facts underlying the debate, including the high failure rates among patron subject searches, driven by the public's overall failure to adequately learn proper controlled vocabulary syntax, and the high percentage of erroneous matches generated by keyword searches, driven by the fact that book titles may have nothing to do with the contents. Describes a hybrid approach that uses a keyword index of the subject field, and that reduces failure rates by 75% among one library's patrons. Reports that, in spite of a few remaining imperfections, this system seems to represent 'the ideal marriage of keyword and formal subject heading searching' for library patrons. Lists the Web site location of the catalogue on which the new system was developed

Abstract: In order to find and correct spelling errors in the online public access catalog at Adelphi University, a visual inspection was performed of the 117.000 keywords indexed in the system. More than 1.000 errors were found. Certain long but common words such as administration, education, and commercial were found to generate many different misspellings. Most of the records were derived from bibliographic utilities, so the findings can be generalized to other OPACs. The same misspellings were also found in substantial numbers in CD-ROM databases. Misspellings were analyzed by the machine-readable catalog (MARC) field in which they were found, part of speech, and type of mistake. Lists of commonly misspelled root words and specific mistakes are included

Abstract

Reviews the potential revolution in the creation and smooth delivery of information on an OPAC released by the MARC 856 field. This offers the catalogue users an active link to a WWW site. Predicts the use of such links for accessing texts or showing locations within the library. Outlines the problems of maintaining the field 856 links and some of the solutions that are being applied by information professionals

Abstract: EPIC, produced by OCLC, is an online computer service for searching the OCLC database using subject, keyword, keyword phrase, and Boolean searches. It is an important new source of information for reference librarians. Reports on the wide variation in its current use. Although welcomed by users as new method of accessing OCLC its automated training program is seen as cumbersome
