Reviews Trueswell's weeding technique, introduces possible application areas, and addresses a number of popular misconceptions. (Author)

It is shown that Trueswell's empirical 80/20 rule arises from type of stochastic model for library loans presented by Burrell and Cane. Particular attention is paid to previously suggested uses of rule in identifying "core collection" for library noting that length of time period is of crucial importance. (20 references) (EJS)

Random samples of monographic materials from U.S. and Canadian public libraries were matched with collections from similar libraries of different sizes. Strong positive correlation appears between percentage find rate and target library size, with regression analysis suggesting linearity over a wide range of collection sizes. (Author)

Measures of classification system performance are suggested and used to evaluate two test collections. Consequences for full-text document systems and online…

Argues that the analytical comparison of library collections to the people using those collections could provide insights related to library acquisition priorities and practices, and describes and illustrates a method for analyzing this relationship. A sidebar by Myra White describes an application of the results of such a study at California…

The data collected for this report can be divided into three segments: a 14-year collection, 1950-51 through 1963-64, on which analyses were performed and the original predictions generated; a six-year follow-up stage, beginning in 1964-65; a twenty-year collection, 1950-51 through 1969-70, from which new predictions were generated; and a…
