Describes PCBIS, a database program for MS-DOS microcomputers that features a utility for automatically converting online public access catalog search results stored as text files into structured database files that can be searched, sorted, edited, and printed. Topics covered include the general features of the program, record structure, record…

Describes minimal-level, or provisional, authority records that are constructed from headings in bibliographic records as part of a computer validation process. Two types of references that can be generated automatically for authority records are explained: (1) those based on other data in the bibliographic record, and (2) those derived from the…

Describes the development and implementation of software that provides a global change capability by allowing correction of a single heading in a large file of bibliographic records through programatic identification and replacement.

Discusses problems of information distortion resulting from romanization (i.e., representation of nonroman scripts in Latin characters) and modifications of USMARC format to support nonroman scripts in library catalogs. Efforts to develop a universal character set and its potential effects on USMARC are considered. (45 references) (MES)

Describes the Multimedia Visualizer, an online public access catalog (OPAC) that uses animated visualizations to make it more user friendly.

Outlines a process for downloading MARC format bibliographic data into a form readable for an Apple Macintosh computer running HyperCard software. Loading procedures for two data sources--an OCLC format tape and records from UCLA's ORION public access catalog--are discussed, and the use of a minicomputer system is considered. (eight references)…

The first of two articles addresses the problems of automated bibliographic control of bound withs--i.e., books or pamphlets published separately and subsequently bound together--in a library collection, and explains a solution devised by Innovative Interfaces. The second article reports on beta testing of KeyNOTIS, a turnkey library automation…

Discusses the importance of maintaining the accuracy and currency of the information in an online library catalog; examines aspects of online catalog maintenance that can be accomplished cooperatively, through networks, or automatically, by computer programs; and describes procedures followed at Washington State University that utilize the Western…

The introduction to a special issue on locally loaded databases in online library systems discusses three trends in using technology to provide greater access to materials available in library collections: unification of local collections; access to outside resources; and inclusion of reference works and full text in online catalogs. (three…

Assesses the current state of reference structures in online public access catalogs (OPACs) in a framework defined by stagnation, progress, and future challenges. Outlines six areas for reference structure development. Twenty figures provide illustrations. (AEF)

Describes Structured Query Language (SQL), the result of an American National Standards Institute effort to standardize language used to query computer databases and a common element in second generation database management systems. The discussion covers implementations of SQL, associated products, and techniques for its use in online catalogs,…

Discusses the traditional alphabetical arrangement of library card catalogs and suggests this order should be reconsidered in online catalogs. Online searching in library catalogs is described; the ordering of records in online catalogs is examined; and filtering is considered as a method to order retrieved sets of bibliographic records. (Contains…

Description of the way in which some essential features of pathfinders have been incorporated in the online library catalog at Lehigh University discusses factors involved in record design, provides examples of records used with a GEAC Integrated Library System, and suggests several ways of implementing pathfinder records online.
