Jail, including claims made by officials that ‘leisure libraries’ exist inside the walls, though their use of the term is vague. The Pittsburgh Current has spoken to a multitude of people to try to understand how many books are inside the jail, how accessible they are to inmates, and whether official descriptions of a leisure library on every pod are accurate.”
