After several weeding excursions into the reference collection at the University of Toledo's Carlson Library, reference librarians realized that the collection had outgrown not only the available shelving space, but possibly also its usefulness to patrons. With the approval plan acquisitions and purchase requests coming from all academic areas on campus, including the library, materials were constantly added to the 30,000+ volume collection. We were experiencing "crisis weeding" (Engeldinger, 1990) where the subject areas with high-use items were weeded and subject areas with less perceived use were left undisturbed. Unfortunately, there was nothing but anecdotal evidence on whether those materials were needed and used by our clientele. In addition, the collection development policy for the reference collection seemed vague and passé. In 1994, the reference staff decided to gather information systematically on the use and the users of the reference collection, with the goal in mind to formulate a viable collection management policy.
