A Cost Effectiveness Model for Comparing Various Circulation Systems
Get PDFTwo models for circulation systems costing are presented. Both the automated and the manual models are based on experience gained in the analysis of circulation services at Washington State University library. Validation tests for the model assumptions are devised and explained. Use of the models for cost effectiveness comparison and for cost prediction are discussed and examples are given showing their application
Cumulating the Supplements to the Seventh Edition of LC Subject Headings
Get PDFA description is presented of the project of the University of California Library Automation Program to cumulate the 1966 through 1971 supplements to the Library of Congress Subject Headings. The University of California Institute of Library Research MARC processing software, BIBCON, was used, with specially written programs. The resulting cumulation was edited, printed in book form, and made available to libraries. The final task involved merging six MARC files into one file of over 125,000 records and then printing that file in a format similar to that of LC Subject Headings. The project was a cooperative effort with participation by people from several UC campuses
File Structure for an On-Line Catalog of One Million Titles
Get PDFA description is given of the file organization and design of an on-line catalog suitable for automation of a library of one million books. A method of virtual hash addressing allows rapid search of the indexes to the catalog file. Storage of textual material in a compressed form allows considerable reduction in storage costs
On-Line and Back at S.F.U.
Get PDFSimon Fraser University library began operation with an automated circulation system. After deliberation, it mounted the first phase of a two-phase online circulation system. A radically revised loan pol·icy caused the system design and assumptions to be called into question. A cheaper, simpler, and more effective off-line system eventually replaced the on-line system. The systems, fiscal, and administrative implications of this decision are reviewed
Providing Bibliographic Services From Machine-Readable Data Bases--The Library's Role
Get PDFLibraries will play a key role in providing access to data bases, but not by subscribing to tape services and establishing local processing centers as is commonly assumed. High costs and the nature of the demand will make this approach unfeasible. It is more likely that the library's reference staff will develop the capability of serving as a broker between the local campus user and the various regional or specialized retail distribution centers which exist or will be established
Statistical Behavior of Search Keys
Get PDFIn discussion about search keys, concern has been expressed as to how the nunber of items tetrieved by a single value relates to collection size. This paper creates a statistical model that attempts to give some insight into this behavior. It is concluded that, in general, the observed behavior can be explained as being intrinsically statistical in nature rather than being a property of specific search keys. An attempt is made to relate this model to other tesearch, and to indicate how this model may be made to yield more accurate predictions
