Describes a model which uses patron arrival rate, length of time on the terminal, and library service policies to determine the minimum number of terminals needed. The model is then used to compare the effects of various service policies on the minimum number of terminals. (CLB)

Presents results of a study that examined the effectiveness of adjacency operators in improving precision and recall in FirstSearch title keyword searches. Compared subject headings of retrieved items to sample title subject headings and discovered that when keywords were limited in meaning and adjacency operators were used, precision was…

Discusses resource sharing among libraries based on a study of data from the Illinois Library Computer Systems Organization (ILCSO). Highlights include differences in borrowing patterns based on the size of libraries, lending/borrowing ratios, and the volume of resource-sharing activity compared to other factors. (LRW)

Describes a survey that examined ways in which users interacted with the authority control of online catalogs developed commercially and locally.

Describes a project in which graduate students with knowledge engineering experience used five different microcomputer-based shells to build a prototype application of an expert system to assist library patrons with business reference questions. The strengths and weaknesses of each product are discussed and compared. (seven references) (CLB)

A study was conducted at Texas A&M University that compared the intactness (i.e., the presence or absence of a bibliographic record) and the accuracy of the bibliographic data in the public card catalog and in the online catalog (ALIS II). Results indicate the online catalog was less intact, but more accurate. (two references) (LRW)

Describes an automation project at the Merriam Center Library in which Apple Macintoshes were introduced as library workstations. The implementation process, staff involvement and reactions, and current configurations and applications of the workstations are discussed.
