Complete the login form, click "Submit," and the message displays that your request was successful. Please see our holds FAQ for pick-up information.

For books, a recall notice will be emailed to the patron automatically when you place your request. The patron can use the book for a minimum of 21 days and has 7 days to return the recalled book. If the hold is placed within 4 days of the book’s loan period, the due date will not be altered.
