Do they sell used books?

No, the old library on the corner of Dogwood and Earp is the friends of the Belleview library's book store, that is where you eill find used books, they are open Thursday, Friday and Saturday from 10-2 and their phone number is 245-2767

Good Morning Lisa, Friends of the Library sell books at some Marion County Library locations: https://www.marioncountyfl.org/departments-agencies/departments-o-z/public-library-system/library-info/friends-of-the-library
