Print materials may be selected for weeding and withdrawing when they become outdated, are in need of repair, or do not reflect Oxford's current curriculum. All withdrawn items are removed from OCLC, Alma, and donated to Better World Books.
Donated books that have been gifted to the library are analyzed for their value to the collection and are either retained or donated to Better World Books.
