Reynolds, Dennis – Information Technology and Libraries, 1982
Reports a survey conducted by the Bibliographical Center for Research to determine the extent of variations for entering local data on the part of BCR OCLC libraries. The results are presented along with a discussion of alternative practices and their impact on the processing of OCLC tapes. References are included. (Author/RAA)

Kilgour, Frederick G. – Library Journal, 1979
Survey findings indicate that inclusion, even partial inclusion, of holdings of academic libraries in an online union catalog significantly accelerates interlibrary lending by those libraries; e.g., six years after initial participation in OCLC, 37 Ohio libraries were lending 75 percent more material.

Persin, Michael; And Others – Journal of the American Society for Information Science, 1996
Discusses ranking techniques for document retrieval and proposes an evaluation, or filtering, technique that reduces costs and memory usage by early recognition of which documents are likely to be highly ranked. Highlights include index design, ranked query evaluation, reducing the number of accumulators, inverted file structures, and experimental…

Garman, Nancy – Online, 1986
Describes a survey of 39 database publishers concerning their policies for downloading, i.e., capture of information into machine-readable format from proprietary databases. Discussion covers fair use principle, long-term storage and reuse, policy enforcement, and per record payment principle. Database publishers surveyed profile of survey…

Reddi, Arumalla V. – Information Processing and Management, 1983
Analyzes computer terminal memory performance in terms of overflow probability and average queueing delay, and presents new method to derive a closed expression for data arrivals with Erlangly distributed interarrival times and an approach to derive steady state probability expressions of the terminal memory content process. Twenty references are…

Reddi, Arumalla V. – Information Processing and Management, 1984
Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…

Lukes, John A. – 1985
This report discusses the development and characteristics of the Prospective Student Inquiry Data File and Information System, which is used by the California State University at Chico (CSUC) as part of an effort to increase its student applicant population. Following a brief review of organizational background information, the report is divided…

Cohen, Malcolm S. – 1975
The report describes an experimental study involving an on-line placement system in Boulder, Colorado which permitted applicants to request information from a terminal on any job stored in the computer. Data were collected on applicants referred by the Employment Service: whether or not hired, reason for not being hired if not hired, applicant…

Horenstein, Bonnie – 1981
In order to determine how the Online Computer Library Center (OCLC) is actually used by its members, in October 1980 a survey was distributed to the head catalogers of 95 academic libraries participating in OCLC in New York State. The 32 question survey was designed to: (1) collect information on the use of OCLC in academic libraries; (2) survey…

Martin, Thomas H. – 1974
The command language features of 11 on-line information retrieval systems are presented in terms of the functional needs of a searcher sitting at a terminal. Functional areas considered are: becoming familiar with the system, receiving help when in trouble, regulating usage, selecting a data base, formulating simple queries, expressing single…

Cohen, Malcolm S. – 1975
The purpose of the research described in the report is twofold. First, it is to analyze the relative benefits and costs of on-line computerized placement systems. The techniques developed for such an analysis which might be useful in evaluating other manpower programs are presented. Second, it is to provide a prototype model which shows how…
