The Friends of Los Alamos County Libraries is a 501c3 nonprofit organization that operates a bookstore just inside the entrance to Mesa Public Library in Los Alamos NM. The bookstore is operated by an all volunteer staff, and we sell used books. In fact, we are the longest-operating used books bookstore in Los Alamos County! Some of the books are from the Library, but most are donated by local residents. All profits from the sales are donated back to the County Libraries, including Mesa Public and the White Rock Library.
