Libraries typically lend books, not sell them. However, many libraries hold book sales to remove older, damaged, or surplus materials from their collections. These sales offer patrons the opportunity to acquire books at very low prices. Occasionally, a library might sell specialized publications, local histories, or other unique items directly. Libraries may also offer withdrawn materials for sale online through platforms like Better World Books.
Disposing of books through sales benefits libraries by creating space for new materials, generating revenue for library programs, and making affordable reading materials accessible to the community. Historically, library book sales have served as a valuable resource for book collectors and readers seeking bargains. These sales also contribute to sustainable practices by promoting the reuse of books and reducing waste.
