Describes a survey of research libraries with online catalogs planned or in place that examined the status of card catalogs, shelf list files, and the capability of online systems to handle traditional shelf list functions. The functions examined include inventory control, collection assessment, holdings information, and call number assignment.…

Presents a model that calculates the conditions under which a library may adopt a highly service-oriented online catalog access policy at minimum additional cost. The use of arrival rates, service rates, and queueing calculations to arrive at a cost-effective policy is explained. (Author/CLB)

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)

Describes a technique for accessing a library system with limited interconnectivity by connecting the system to a gateway machine that is a host in the local area network and evaluates the performance of an existing prototype that has been implemented at the Los Alamos National Laboratory. (Author/CLB)

Reports the results of a survey of libraries having authority control and using authority control vendors, which was conducted to examine online maintenance features of present systems. The features discussed include global updates; uniqueness, hierarchical, and reciprocity checks; human intervention; field validation; and frequency of authority…

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. An appendix provides a comparison of current microcomputer based workstations…

Proposes a rationale to be used in comparing and evaluating alternative library computer catalogs, based on varieties of bibliographic data processed, kinds of indexes constructed, and desired search strategies. A glossary of terms related to computerized catalogs is appended. (Author/CLB)

Discusses the need to teach undergraduate students the critical thinking processes necessary to formulating and researching a topic, rather than the technicalities of online catalogs. The development and design of an online catalog at Dickinson College, which forces students to make informed choices throughout the search process, is described.…

Describes the power of queuing models as a source of detailed, expected performance measures for online catalogs. An illustration of such a performance analysis is provided, and its value to library administrators is discussed. (9 notes with references) (CLB)

Reviews key developments in information technologies, and describes the possible convergence of these developments in the creation of a new publishing and communication medium. The impact of this technology on the organization and role of libraries is discussed. (4 references) (CLB)
