BELLTIP is an on-line library processing system concerned with book acquisitions, cataloging, and financial accounting for a newwork of 26 technical libraries. At its center is an interactively updated and queried set of files concerned with all items currently in process. Principal products include all purchase orders, claims, and cancellations;…

The main instrument of data collection in this survey of library technical processing centers was a questionnaire sent to 16 network coordinators.

Reviews a study which examined computerized bibliographic centers in Canada identifying three types: (1) library processing facility; (2) library network user group; and (3) information retrieval facility. The study also reported on ways to promote a computerized library network with emphasis on national location service. (CWM)

The inputs to mathematical models of library operations require periodic updating. The data collection effort necessary for such updating can be quite expensive; however, if the data collected can serve multiple purposes, the costs can perhaps be justified. A management information system (MIS) offers a vehicle for multiple uses of data, and thus…

Discusses hypotheses which examine, for a nonprogramed decision, variables of (1) individual decision makers, (2) information upon which choices are based, and (3) structural features within which decision is made. Circumstances under which decision-making group (Ohio's librarians) selected an innovative alternative (incorporation of OCLC) are…

Discusses the design of a model-based management information system in terms of mathematical/statistical, information processing, and human factors issues and presents a prototype system for interlibrary loan networks. (Author/CWM)

Progress on the development of a mathematical model and associated computer programs for use by the Illinois State Library in evaluation and planning of the interlibrary loan (ILL) network is summarized. Pertinent published literature on ILL networks is reviewed in terms of network structure, operations, satisfaction of requests, and costs. A flow…

BALLOTS is a computerized system to support acquisitions and cataloging in the Stanford University Libraries.
