91´«Ã½ 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 collection development or selection 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.

Georgia Public Library Service. Collection Development.

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.

Kelly, Mary, and Holly Hibner. . Awful Library Books: Hoarding is not collection development. Internet resource.

Weeding is an essential component of library collection management. Most libraries simply do not have unlimited space, and we must continually make room for new materials. Weeding is necessary to remain relevant to our users and true to our missions. Remember – unless your library exists to archive and preserve materials for the ages, we are not in the business of collecting physical things. We collect information and provide access to information. We love books as much as anyone else, and sometimes hard decisions have to be made. How many times have you said, "But I just bought that!" and then realized it was ten years ago?

Librarians, bibliophiles, and lovers of nostalgia are all welcome here. Your librarians for this site are Mary Kelly and Holly Hibner. We are public librarians in Michigan. We have both been holding court at various reference desks for over ten years and love talking about library collections and library service. We also regularly present and consult on various library topics. (This blog was actually a result of one of those presentations. Read more about that on .) This site is a collection of library holdings that we find amusing and/or questionable for libraries trying to maintain a current and relevant collection. Contained in this site are actual library holdings. No libraries are specifically mentioned to protect our submitters who might disagree with a particular collection policy. (A good librarian would probably be able to track down the holding libraries without too much trouble anyway…) Our posts come from our travels, snooping in library catalogs, and from library staff all over the world. Please join in the fun and send us your finds. Go to to find out more details. Comments are welcome and moderated, but we do ask everyone to be nice and use your library voice. You are welcome to any of our images and text, but please link back to us or give us credit. Librarians love a good citation!

Larson, Jeanette. . Austin, TX: Texas State Library and Archives Commission, 2008.

Revised in 2012 to include a section on e-books! For more than 30 years, The CREW Method has provided guidance to librarians and staff in small and medium sized public libraries about how to cull outdated and no longer useful materials from their collections. Since its inception in 1976, The CREW Method has become the benchmark tool for weeding library collections. It has been more than a decade since the first revised edition brought technology and online catalogs into the process. This new edition, called CREW: A Weeding Manual for Modern Libraries, builds on the work of Joseph P. Segal and Belinda Boon. Although much of the basic information remains the same, the impact of changes in technology and its effect on library collections has been taken into consideration. The CREW guidelines by Dewey Class have been expanded even further and updated to reflect current practices. New sections have been added that explain in more detail the MUSTIE factors and types of disposal. The bibliography has been updated to include current editions of standard works, contemporary selections, and expanded online resources.
