Updates the data on the occupational structure of information work. Patterns of information sector employment are described, changes in occupational structures are discussed, and data that indicate that the information sector continues to grow as a proportion of all employment is examined. (Author/LRW)

The average citation per article in chemistry by age of citation is related to the Poisson frequency distribution. This provides a formula for calculation of a half-life for chemistry which depends on the structure of the research front exhibited in the literature. (Author/FM)

Discussion of changes in organizational environments focuses on nonbureaucratic, or nontraditional, organizations, and the role of information technology. A model of a nontraditional organizational design is described and results of a pilot study of the role of information technology in nontraditional organizations are presented. Contains 114…

The scientific information diffusion theory is used to explain the increased citation frequency of recently published articles in respect to the normal exponential decay of older articles. Appendices illustrate this approach. (Author/FM)

Reexamines the feasibility of automatic thesaurus generation by establishing a framework for analyzing the degree of correspondence between automatically generated thesauri and a thesaurus of the same terms constructed by subject specialists. (Author/FM)

Describes an operational trial of computer-aided information processing methods conducted by a National Science Foundation program office in an effort to show that staff productivity increases with computer augmentation. (FM)

Activities within a library are combined with the library's floor plan to develop a model of the library as a network of queues. This model can be used to predict average patron processing times and costs as they are affected by demand characteristics and floor plan variations. (Author/FM)

Two methods are presented by which the librarian can forecast book circulation by subject. The shelflist model treats the number of library books as a control variable, while the other defines the dependent variable as the proportion of the shelflist circulated. (FM)

Describes the services and resources of the San Mateo Educational Resources Center (SMERC) and presents the results of a survey of linking agents operating within SMERC contracts, including findings about their organizational settings, educational backgrounds, marketing activities, and perceptions about the usefulness of the service. (FM)

Exploring the use and effectiveness of current awareness (CA) methods, especially selective dissemination of information (SDI) among chemists at Canadian universities, this study focuses on the perceived dispersal of information, use of various CA methods, time spent on CA, perceived success in CA, and CA efficiency. (FM)

Illustrates a method to divide large citation database files into clusters of journals without requiring the use of arbitrary starting points. Results are discussed relative to biomedical literature. (Author/FM)

Presents a method of using library patrons' perceived needs for titles as a means of ascribing scholarly journal collection support and costs to academic programs. (Author/FM)

Discussion of users and information retrieval systems highlights a study that investigated the representation of users' knowledge by examining their names for objects and concepts, agreement on names, the Library of Congress Subject Headings representation for similar objects and concepts, and measurement of the similarity between these…
