Alcatraz Library

Upon entering the prison, every inmate was issued a library card and a catalog of books contained in the library. Inmates could place an order for books prior to breakfast and have the books delivered to their cell. They were permitted a maximum of three books, 12 textbooks, a Bible and a dictionary at one time.
