Lately there have been many posts in library weblogs about weeding issues. I won't comment on them. Each library is unique and must make decisions about what is best for them. However, it does give me the opportunity to point to the Weed of the Month Club. Each month for many years they examined a subject area and then gave some guidelines and pointed out some books commonly in collections that should be considered for weeding. Intended for school libraries, it can be used for public, community college and in some instances academic and special libraries. A great resource. A book has been published based on the project Less is more : a practical guide to weeding school library collections by Donna J. Baumbach and Linda L. Miller.
