Recalls (or request) are a way for the library to ensure that all borrowers have equal access to its print resources. If a book you need is checked out, you may recall it from the current borrower , who will have 3 days to finish with it and return it. Conversely, if someone needs a book you have checked out, they may recall it from you, and you will receive a notice letting you know that you must return the book within 3 days.
