FAQ: Why did I receive copies of a book from two different libraries even though I placed only one interlibrary loan request?

Chances are one of the libraries sent you the book without changing the status of your request to Shipped so the request moved down your lender string and was answered by another library. In this instance, only the book sent by the second library is tracked in the system. Treat the other book as if it had been an e-mail or phone request. When you change the request status to Returned, make sure you’re sending back the correct library’s book.
