Cancelled requests:a study of interlibrary loan requests for items held in a medical library collection

This paper presents the results of a study to document and analyze a sample of interlibrary loan requests received from library patrons of an academic medical library for items that are actually held in the collection of the library. This category is referred to as cancelled requests. The purpose of the study was to attempt to measure the degree to which library patrons are not making the best possible use of the collection and understand why this was taking place. Suggestions are presented for steps to lower the cancellation rate.
