An Interactive Computer-Based Circulation System for Northwestern University: The Library Puts It to Work
Get PDFNorthwestern University Library's on-line circulation system has resulted in dramatic changes in practices and procedures in the Circulation Services Section. After a hectic period of implementation, the staff soon began to adjust to the system. Over the past year and a half, they have devised ways to use the system to maximum advantage, so that manual and machine systems now mesh in close harmony. Freed from time-consuming clerical chores, the staff have been challenged to use their released time to best advantage, with the result that the "service" in "Circulation Services" is much closer to being a reality
Computer-Based Subject Authority Files at the University of Minnesota Libraries
Get PDFA computer-based system to produce listings of topical sub;ect terms and geographically subdivided terms is described. The system files and their associated listings are called the Subject Authority File (SAF) and the Geographic Authority File (GAF). Conversion, operation, problems, and costs of the system are presented. Details of the optical scanning conversion, with illustrations, show the relative ease of the technique for simple upper case data files. Program and data characteristics are illustrated with record layouts and sample listings
Automation of Acquisitions at Parkland College
Get PDFThis paper presents a case study of the automation of acquisitions functions at Parkland College. This system, utilizing batch processing, demonstrates that small libraries can develop and support large-scale automated systems at a reasonable cost. In operation since September 1971, it provides machine-generated purchase orders, multiple order cards, budget statements, overdue notices to vendors, and many cataloging by-products. The entire collection, print and nonprint, of the Learning Resource Center is being accumulated gradually into a machine-readable data base
Personnel Aspects of Library Automation
Get PDFPersonnel of an automation project is discussed in terms of talents needed in the design team, their qualifications and organization, the attitudes to be fostered, and the communication and documentation that is important for effective teamwork. Discussion is based on Stanford University's experience with Protect BALLOTS and includes comments on some specific problems which have personnel importance and may be faced in major design efforts
An Algorithm for Compaction of Alphanumeric Data
Get PDFDescription of a technique for compressing data to be placed in computer auxiliary storage. The technique operates on the principle of taking two alphabetic characters frequently used in combination and replacing them with one unused special character code. Such une-for-two replacement has enabled the ILO to achieve a rate of compression of 43.5% on a data base of approximately 40,000 bibliographic records
A MARC II-Based Program for Retrieval and Dissemination
Get PDFSubscriptions to the Library of Congress' MARC tapes number approximately sixty. The uses to which the weekly tapes have been put have been minimal in the area of Selective Dissemination of lnformation (SDI) and current awareness. This paper reviews work that has been performed on hatched retrieval/dissemination and provides a description of a highly flexible cooperative SDI system developed by the Library, University of Saskatchewan, and the National Science Library. The system will permit searching over all subject areas represented by the English language monographic literature on MARC
Title-Only Entries Retrieved by Use of Truncated Search Keys
Get PDFAn experiment testing utility of truncated search keys as inquiry terms in an on-line system was performed on a file of 16,792 title-only bibliographic entries. Use of a 3,3 key yields eight or fewer entries 99.0% of the time
