As librarians, part of our job is to ensure the thoroughness, relevance, timeliness, and usefulness of the library collections. Weeding ensures that the materials that remain in the collection are useful and accessible. Our collection needs to be continually added to and withdrawn from to reflect changes in the curriculum, society, and the library’s goals.
“When libraries do not weed regularly or consistently, customers have trouble finding interesting and relevant materials. Removing outdated or worn-out items makes the collection more visually attractive and more inviting to users. Patrons trust the library to supply information that is easy to find and up-to-date. All of these are positive factors from the customer’s point of view. For the librarian, weeding has additional advantages. It finds the gaps in your collection so that you can make new purchases with confidence and creates space for those materials. Paradoxically, weeding is a good way to increase circulation by drawing attention to materials that had previously been overlooked.” - Arizona State Library weeding policy http://www.lib.az.us/cdt/weeding.aspx
