Q. Here are 3 library books that are very overdue. Will I owe any fines or fees?

First; thanks for finding and returning the books. Second; the library does not charge fines for overdue books, with the exception of books on reserve. The fine for overdue reserve books is $1.00 with the maximum fine of $10.00 per item. As long as the material you are returning is not damaged you will not owe any fines.
