Deselction

  1. 1.  “Selection in reverse” Importance: without an on-going weeding program, a collection can quickly age and become easily to use. When libraries, whether large or small library, reach the limit of their collection, their confront 3 alternatives: Acquire new physical facilities, Divide the collection (which also require space), Weed the collection (which may or may not require new space).
  2. 2. H. F. McGraw As “the practice of discarding or transferring to storage excess copies, rarely used books, and materials no longer of use.”Purging As “officially withdrawing a volume (all entries made for a particular book have been removed from library records) from a library collection because it unfit for further use or is no longer needed.” Applies more to library’s file than to items in the collection.
  3. 3. Stanley J. Slote Is “removing the noncore collection from the primary collection area [open stack area].
  4. 4. DISPOSING Forms: exchange programs, Friends of Library book sales or sale to an out-of-print dealer for credit against future purchase.STORING Retains the item at a second level of access. Second level of access normally is not open to the client and frequently some distance from the library. For Academic library: on or off campus storage unit. For public lib: under their own custody.
  5. 5.  Primarily supplying materials that meet the current needs and interests of a diverse community of users. User demand is the important factor influencing selection and deselection; materials no longer of interest or use are candidates for storage or disposal. Ideally, as for discarding, a public library rule of thumb is that collection should turn over once every 10 years.
  6. 6.  There are differences (responsibilities) due to size: Small and branch public libraries focus on high demand materials, with little or no expectation that they will have preservation responsibilities. Large public libraries often include housing and maintaining research collection, they have to consider a wide range of issues (materials) when undertaking a deselection program.
  7. 7. A survey of North American public libraries’ weeding practices, 2002 294 libraries in Canada and USA 5 Top reasons for weeding: Accuracy/ currency of information Physical condition Space needs Usage history Duplicate copy
  8. 8.  Weeding Library Collections, Stanley J. Slote. Relying on circulation data (shelf life) to identify candidates for weeding. The CREW Method: Expanded Guidelines for Collection Evaluation and Weeding for Small and Medium-Sized Public Libraries, Belinda Boon and Joseph P. Segal. MUSTIE (M= misleading, U= ugly [worn-out], S= superseded, T= trivial, I= irrelevant to your needs, E= available elsewhere) CREW (Continuous Review Evaluation and Weeding)
  9. 9.  Deselection is easier because of comparatively straightforward and predictable use of patterns, the small size and homogeneous nature of clientele, and relatively narrow service goals for the library. Deselection takes place with little hesitation because costs and space are prime considerations.
  10. 10.  Traditionally, the purposes of academic research library have been to select, acquire, organize, preserve and make available the full record of human knowledge. Collection development officers seldom view demand as a valid measure of item’s worth. Potential or long-term research value takes highest priority.
  11. 11.  Have slightly better track record of securing funding (for additions to their buildings, new buildings), they, too, face finite collection space and a mission goal of preserving information resources, thus deselection has become part of academic library life cycle. Bulk of the academic “weeds” go into some type of lower-cost storage unit either on or off campus.
  12. 12.  When compact shelving is closed to the public, one has the option of changing how one houses the stored material.
  13. 13.  Employed highly structured collection development practices. The need to coordinate collection development with the curriculum needs is imperative, more particularly when there is a major shift in the curriculum; the library must remove most of the old material. To some degree, the media center’s deselection problems are fewer, other library serve as backup resources.
