Simon Fraser University library began operation with an automated circulation system. A radically revised loan policy caused the system design and assumptions to be questioned. 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…

The on-line union list currently being developed by the University of Pittsburgh and libraries of the Pittsburgh Regional Library Center is described, including information on present procedures, future plans, and format for local data records agreed upon with OCLC. (Author/KP)

Describes the usage and advantages of microcomputers as an alternative to manual processing when the Great Neck Library minicomputer-based automated circulation system goes down for maintenance or repair. (RAA)

The results of a study carried out under the auspices of the Council on Library Resources are described. (Author)

Described is the file organization and design of an on-line catalog suitable for automation 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.

Presents a practical guide for the implementation of a turnkey circulation system for those contemplating purchase of an online system. Included is advice on staff planning and bibliographic and patron file conversion. Weaknesses and strengths of the automated system are summarized. (Author/RAA)

The development of a terminal and the adaptation of bar-coded labels for the University of Chicago on-line circulation system are described. (PF)

A model to calculate the costs of automated cataloging systems based on cataloging copy in a system's data base is developed. The costs derived by the model for two systems, OCLC and BALLOTS, are compared to the costs of an existing manual system. (Author/KP)

Four categories of automated network catalog products and services are examined. The advantages and disadvantages of (1) the on-line cathode-ray-tube (CRT) display, (2) the line-printer produced card, (3) the photo-composed book catalog or catalog card, and (4) computer-based microforms are all reviewed.

Gives an overview of MEDLARS II as an example of a major bibliographic processing system that supports on-line access to a number of very large files, has efficient throughput, and is operated on a single large-scale computer. (Author/PF)

Describes the generation and utilization of financial reports by the online book order system developed at the University of Massachusetts. A series of reports record monthly book transactions, use of funds by subject and type of publication, and the performance of vendors. (Author/RAA)

On-line circulation systems divide into two types. One type contains records only for charged or otherwise absent items. The other contains a file of records for all titles or volumes in the library collection, regardless of their circulation status. This paper traces differences between the two types.

Traces the development of circulation systems through the librarian's perception of circulation control and the technology of modern online systems. Librarians have switched from a broad service approach to a narrow record keeping approach and back again as technological innovation has expanded their viewpoints. Included are six references.…

Explains how a multipurpose bibliographic/MARC data base of machine-readable data files (MRDF), created according to the MARC II record format, was conceived, and how much an information resource would benefit the general user and professional librarian. (Author/CWM)

Suggests that catalogs of the future, as facilitated by computer technology, should take on multiple formats. Three levels of varying form and size are envisioned for the needs and uses of the librarian, the general user, and the individual user. (Author/RAA)
