Comparisons of "hard" and "soft" science in a user study and a citation study are shown to exhibit a previously unnoticed complementarity. (Author/PF)

A model identifying seven principal dimensions of information systems and sources is developed and tested. The dimensions are defined in terms of required user behavior, with an associated scale indicating differential levels of this behavior. Both system design behavior and probable use behavior information in compatible forms are yielded. (15…

A journal evaluation study was conducted at the National Oceanic and Atmospheric Administration (NOAA) libraries to assist in subscription renewals, collection relevance enhancement, and determination of efficient methodology. Data collection included a use study, circulation and inter-library loan statistics, core journals, questionnaires, costs,…

Traces the history of the field of bibliometrics from ancient times to 1969, when the term was proposed as a substitute for "statistical bibliography," and discusses the theories of Lotka, Zipf, and Bradford; library use studies; citation analyses and bibliographic coupling. (Author/EM)

The findings of this investigation are based upon an analysis of actual use data recorded from all volumes and issues left by library users on study tables and on trucks in the photocopy area. (27 references) (Author/SJ)

The two objectives of this study were to determine the acceptability of the microfiche format as a medium for reading technical reports among a representative group of engineers and scientists, and to measure the effects of using this medium as the reading habits of the group.

Searches of OCLC revealed that 65 percent of a Canadian special library's recent acquisitions had already been cataloged. This percentage compares favorably with similar libraries in the U.S., and suggests that technical information centers and special libraries throughout North America could benefit from OCLC participation.

There is evidence which suggests that users' attitudes toward on-line interactive retrieval systems may be multi-dimensional. Because this earlier work was based upon factor analysis of the data, it was essential that a replication be attempted. To this end a previous study with a new population of users was repeated.

A mathematical model is presented that can be used to predict a library's circulation. (Author)

Data for the raw frequency of use of 138 physics journals in the science library at MIT are re-examined and converted to densities of use-per-metre of shelf. There is no evidence for synchronous obsolescence in the 1955 to 1968 volumes, and some evidence of greater density of use with greater age. (Author/LS)

The research reported here deals with the formulation and subsequent evaluation of different promotional programs for a batch-processed current awareness service provided by the Mechanized Information Center (MIC) at Ohio State University. (7 references) (Author)

Two measures of effectiveness for university libraries are constructed: the primary, defined over the total population of users, considers the number of information items desired, number of satisfactorily answered inquires, and number of users; while the secondary, total population is divided into subsets according to similarity of user needs. (13…

Compares raw-use ranking of journal titles held in libraries with dividing the raw-use frequency of titles by the actual linear shelf space of the title's file to obtain a density-of-use rank. The quality of the differences between the two methods is evaluated. Thirteen references are cited. (FM)

Users of seven MEDLINE information centers were investigated in terms of characteristics, motivations, purposes and expectations in using the service. (Author)
