hello can i return the library books outside of the box that say "books returns" ?

To be clear, you should place the books INSIDE the book return. The return box is located outside the library but the books go inside the book return. Thanks!

You shouldn't get a late fee, you should be able to return up until 8am in that drop box the day after they're due and they'll count them with the day before!

Yeah! I do all the time. Make sure it’s the day before your due date or it may come up as a late fee!
