Title
"Use" as a criterion for the weeding of reference collections
Source
Reference librarian. 1990, no.29, S.119-128
Year
1990
Abstract
Contribution to an issue devoted to the weeding and maintenance of reference collections. Little has been published about weeding reference collections until the past few years and little of that has been empirical research. Reviews the literature on the subject with emphasis on use of the material as a condition for deselection. The University of Wisconsin, Eau Claire Library has collected data for 5 years; Uses this data to show that even in well weeded collections, which previously depended upon subjective methods, empirical data will prove beneficial. Proper reference collection management requires more than subjective judgments. Empirical data may provide a number of surprises. Data collection is being made easier by automation.
