Prince George’s County Memorial Library System’s mission is to help customers discover and define opportunities that shape their lives. We offer print materials, large print books, downloadable books, audiobooks, educational DVDs, over 50 online resources, computer access, wifi, and more at any of the 19 branch libraries. Prince George’s county residents are also eligible for the Books By Mail service if they can no longer visit the library due to visual impairment or physical disability. Books By Mail is a free service through which homebound residents can receive material by mail.
