In order to maintain a vital, current collection which meets the needs of our community, the Carsonville Public Library periodically weeds its collection. An item is removed from the collection when it is obsolete or outdated, worn beyond use, damaged, no longer circulating or being used for reference purposes, or it is one of may copies of a formerly popular title. A material that is removed because it is worn or damaged may be replaced with another copy of the same title. This replacement will depend on the following factors: the number of copies of a title that a library owns, the availability of the work, the availability of newer material on the subject, the importance of the work in its field, and cost. Standard bibliographic tools are consulted during the weeding process. Withdrawn materials that are still in good condition will sold at the annual booksale.
