Examines how informetric characteristics of information retrieval (IR) system databases can be used to help system designers decide what type of file structures would provide the best performance. The development of appropriate models describing database contents is highlighted in this first part of a two-part study. (30 references) (LRW)

This second report on a two-part study on the application of informetrics to information retrieval (IR) system design used models of database contents in a factorial simulation study at the University of Western Ontario. The study explored whether different file structures were better suited for different informetric environments. (32 references)…

Findings of a longitudinal study indicate high success rates for OCLC as a source of cataloging copy. They further suggest that holding patterns for many types of materials may be unnecessary. (Author/RAA)

Provides statistical data from MARC-II bibliographic files to be used in the design of a nationwide authority file. The data include information on characteristics of headings and on expected sizes and growth rates of various authority file subsets. Although the data are system dependent, some general implications are derived. (RAA)

Presents the results of a survey of small and medium-sized academic libraries conducted to determine the features of an online catalog considered most important by academic librarians. The major requirements of an online catalog most commonly cited by the librarians are discussed and a ranked list of desirable features is included.

Discusses results of opinion poll conducted by Library and Information Technology Association of 334 academic, public, government, and corporate libraries concerning authority control in the online environment. Use of authority files on bibliographic utilities, presence of online catalogs, Library of Congress authority records, and comments from…

Review of research on online public access catalogs sponsored by Council on Library Resources notes the scope and method (questionnaires administered to catalog users and nonusers in 29 participating institutions) and findings and applications (including organizational setting and computer system, catalog use and satisfaction, and implications).…

The purpose of this study was to examine the inter-indexer consistency in the assignment of selected access points between OCLC and RLIN (Research Libraries Information Network). Both databases are used by many libraries as bibliographic sources for copy cataloging. Access points were compared for differences in wording, MARC coding, and…

Describes a statistical study of three databases, conducted at Iowa State University, on holding links between citation databases and the online catalog. Provides insights into the construction and quality control of citation databases and online catalogs, and identifies a new issue of continued maintenance of ISBNs and ISSNs for catalogers.…

Retrievability of titles of 152 periodicals were compared in a fixed-length algorithmic search (Library Computer System) and a keyword search (Washington Library Network) to determine which type of search algorithm is more successful with titles of varying lengths. Three references and a list of English language stopwords are appended. (EJS)

Examines bibliographic relationships within the context of a global bibliographic database. Results of this research indicate that a core of works of similar character constitute the bibliographic population of American academic and research libraries (OCLC, Online Computer Library Center members). The size of a bibliographic family seems to be…

Describes the University of California at Berkeley's participation in the TREC (Text Retrieval Conference) interactive track experiments. Highlights include results of searches on two systems, Cheshire II and ZPRISE; system design goals and implementation; precision and recall results; search questions by topic and system; and results of…

Findings of focused-group interviews conducted for OCLC study of library users and online public access catalogs (OPACs) indicate users like OPACs, have problems finding right subject heading, envision features to improve subject access, want access to more than books, and want OPACs to provide new services. Eight references are listed. (EJS)

Provides detailed model to be used to select most effective method for accomplishing library catalog retrospective conversion. The random sample, gathering information, and steps in project to be costed (searching, verification and editing, coding and input of nonhits, and obtaining final records) are discussed. Examples and eleven references are…

The 3-year retrospective catalog conversion project described involved the conversion of 446,913 selected monographic records of six major New York State research libraries into machine readable format. The records were searched against the OCLC, Inc., data file. If a match or an identical record was found, the corresponding OCLC record was…
