Circulation Systems Past and Present
Get PDFA review of the development of circulation systems shows two areas of change. The librarian's perception of circulation control has shifted from a broad service orientation to a narrow record-keeping approach and recently back again. The technological development of circulation sys-tems has evolved from manual systems to the online systems of today. The trade-offs and deficiencies of earlier systems in relation to the comprehensive services made possible by the online computer are detailed
Multimedia Catalog: COM and Online
Get PDFLike many public libraries, the Tucson Public Library (TPL) is closing its card catalog and implementing a vendor supplied microform catalog. Unlike mos tof these other libraries, however, the TPL microform catalog will not include location or holding information. The indication of where copies of a particular title are actually available (i.e., which of the fifteen possible branch locations) will be availableonly by accessing a video display terminal connected to the online circulation and inventory control system

Application of the Variety-Generator Approach to Searches of Personal Names in Bibliographic Data Bases--Part 1. Microstructure of Personal Authors' Names
Get PDFConventional approaches to processing records of linguistic origin for storage and retrieval tend to regard the data as immutable. The data generally exhibit great variety and disparate frequency distributions, which are largely ignored and which entail either the storage of extensive lists of items or the use of complex numerical algorithms such as hash coding. The results in each case are far from ideal.
The variety-generator approach seeks to reflect the microstructure of data elements in their description for storage and search, and takes advantage of the consistency of statistical characteristics of data elements in homogeneous data bases.
In this paper, the application of the variety-generator approach to the description of personal author names from the INSPEC data base by means of small sets of keys is detailed. It is shown that high degrees of partitioning of names can be obtained by key-sets generated from the initial characters of surnames, fmm the terminal characters of surnames, and from the initials.
The implications of the findings for computer-based bibliographical informationsystems are discussed
Impact of National Developments on Library Technical Services and Public Services
No full textSeveral recently established national programs are evaluated from the point of view of the practicing librarian. It is essential that we be aware of the consequences of adopting these programs, and that planners and librarians communicate adequately
A Computer-Accessed Microfiche Library
Get PDFThis paper describes a user-interactive system for the selection and display of pictorial information stored on microfiche cards in a computer-controlled viewer. The system is designed to provide rapid access to photographic and graphical data. It is intended to provide a library of photographs of planetary bodies and is currently being used to store selected Martian and lunar photography
