Beginning November 1, D.C. Public Libraries — except for Martin Luther King, Jr. Memorial Library — will no longer accept cash as payment for fines and late fees on borrowed materials. The change in policy is due to a new District law which requires armored vehicles to come and retrieve all city revenue from government buildings; obviously, it wouldn’t really be cost-effective for DCPL to pay for armored cars to show up at every single one of its libraries to pick up the small amount of money that they collect. (The late fee on books: a whopping twenty cents per day.) But, really, those of you who are reading this right now shouldn’t need to ever pay a late fee — you can extend the amount of time you can hold your borrowed materials pretty easily online here.
