From February 1 – 14, 2016, the Los Angeles Public Library (LAPL) will welcome back its overdue books and the people who love them. During these two weeks only, you can return overdue materials to any of the 73 libraries and LAPL will forgive your past and present fines. Your record will be cleared and you can use your library card again.

From the Los Angeles Sentinel:
We are thrilled to offer people this unique opportunity to reunite their overdue books with our library shelves with no questions, no judgment and best of all, no fines,” said City Librarian John F. Szabo. “We’re encouraging everyone—children, students and adults—to return their overdue materials so they can get back to discovering all that the library has to offer, and so others can enjoy these books.”
