Weeding Library Collections: A Selected Annotated Bibliography for Library Collection Evaluation

ALA Library Fact Sheet 15

"Next to emptying the outdoor bookdrop on cold and snowy days, weeding is the most undesirable job in the library. It is also one of the most important. Collections that go unweeded tend to be cluttered, unattractive, and unreliable informational resources."

- Will Manley, "The Manley Arts," Booklist, March 1, 1996, p. 1108.

There are two aspects to weeding. The first is the writing of a collection development or selection policy that is appropriate for your community; this will serve as a guideline as you make decisions about your collection. The second is applying that policy as you make decisions about the materials in your collection. This fact sheet offers a selection of resources for collection development and evaluation, many applicable to all types of libraries and others for specific types of libraries.

As the authors put it in their introductory chapter, "whatever environment one works in, collection development is an exciting challenge that requires lifelong learning." 

 

Georgia Public Library Service. Collection Development.
http://www.georgialibraries.org/lib/collection.html

Each public library system in Georgia seeks to provide a collection of materials, in a variety of formats, which reflect the diversity of the population served, and of American society. In the collection, as many points of view are included as possible. It is important that each library system drafts, and has approved, a written collection development policy. The Georgia Public Library Service provides guideline documents and bibliographies to assist Georgia public libraries in completing this task. Includes resources, with guidelines and bibliographies, on collection standards, policy development, core collections, opening day collections, as well as weeding.

Doll, Carol Ann, and Pamela Petrick Barron. Managing and Analyzing Your Collection: A Practical Guide for Small Libraries and School Media Centers. Chicago: American Library Association, 2002.

If you can follow a cookbook, you can use these simple "recipes"—calculations, formulas, and measurements—to come up with statistics for analysis and management of your collection. Using measures of timeliness, relevancy, use percentages, user profiles, and comparisons, you can determine in quantitative ways the quality of your library's collection. From there, you can communicate its value to your customers. By gathering concrete statistical evidence, you will be in a position to weed appropriately and make decisions about future market-targeted acquisitions. An added bonus is that you can create a research-based profile of your total library—its collection and users—that you can present to budget-makers and potential funders. These time-tested, step-by-step directions show even the most math-phobic how to: gather and analyze data produced by automated systems; conduct a random sampling using one of three easy-to-execute methods; evaluate all types of information formats including books, videos, periodicals, and CD-ROMs; provide hard evidence to decision makers; improve collections with smart weeding to make way for new acquisitions; and estimate the cost of updating your collection.
