The first of a two-part series covers research published since 1970 that is directly relevant to interlibrary loan in the United States, with emphasis on studies of total volume, growth rate, nature of exchange relationships, characteristics of requests and types of material requested, users and uses, and financing.

Circulation time-series data from 50 midwest academic libraries were used to test 110 variants of 8 smoothing forecasting methods. Data and methodologies and illustrations of two recommended methods--the single exponential smoothing method and Brown's one-parameter linear exponential smoothing method--are given. Eight references are cited. (EJS)

Describes a practical study to demonstrate trend analysis and several related statistical instruments that can be applied to library research, presents possible topic for full study, and substantiates author's view on future of libraries. An overall analysis of variance is presented and examples of data analysis are appended. (13 references) (EJS)

Analyses of the relationship between costs and output in more than 3,000 United States academic libraries show that average costs rise more rapidly than output for all types of libraries except two-year private colleges. Major differences in workload and expenditures were found between two-year and four-year public and private institutions. (EJS)

Describes a study at the University of Michigan that examined the extent of serials duplication among branch and divisional libraries, the portion of the serials budget made up of duplications, and the relationship between duplication and serials characteristics. Ways to avoid serials duplication are suggested based on the findings of this study.…

Analyzes a sample of over 4,700 orders for library materials at the University of California, Berkeley, in terms of the probability that the material will arrive and the factors that determine arrival. Models to evaluate the book ordering process are presented, and variables that may affect arrival time are discussed. (six references) (Author/LRW)

Discussion of interlibrary loan transaction fees and their effect on user requests focuses on a case study of the library of the State Historical Society of Wisconsin. Comparisons are made between charging and noncharging conditions, and it was found that only public libraries showed a decrease in interlibrary loans after fees were initiated. (31…

Reports results of a study that examined academic library holdings for core journals in genetics and economics to identify quantitative and qualitative journal characteristics that are predictors of the number of libraries subscribing to the journal. Variables investigated include subject area, publisher, price, longevity, impact factor, prestige…

Reports results of a survey of authority control/database maintenance librarians in 151 major academic and research libraries in the United States and Canada that investigated the current state of automation change, reactions of technical services staff to changes, and methods used to train staff in the changed technology. List of surveyed…

Construct validity and reliability estimates indicate that study designed to measure utilization of automation in public and academic libraries was successful in tentatively identifying and measuring three subdimensions of level of automation: quality of hardware, method of software development, and number of automation specialists. Questionnaire…

Analysis of data collected from two sample surveys assessing change and direction of change in education for librarianship among academic librarians indicates increases in advanced degrees held or being pursued beyond the M.L.S. and in courses, workshops, and conferences attended. Disparities were found between male and female educational…

Four models for conceptualizing a circulation matrix containing the number of books borrowed according to subject and majors of student borrowers compare (1) majors; (2) subjects; (3) disciplines, suppressing the distinction between majors and subjects; and (4) majors with subjects. Results of multidimensional scaling analysis of the models are…

Causal regression and time series models were developed using six years of data for home borrowing, average readership, and books consulted at a university library. The models were tested for efficacy in producing short-term planning and control data. Combined models were tested in establishing evaluation measures. (10 references) (Author/MES)

Citation analysis of the journal "Signs: Journal of Women in Culture and Society" was shown to be a useful tool for defining the core collection for a women's studies program. Analysis over a 10-year period produced a list of 20 of the most frequently cited journals for women's studies and related fields. (six references) (LAE)

Comparison of return rates of materials from Ohio State University Libraries to other home loan studies for academic staff and students indicates that due date may be less important than previously thought, and publicity should be tested as means to encourage students to return materials at earlier date.
