Q. What is a standard loan for a book?

A standard loan item is issued for 21 days and for 7 days if someone else is has requested the item and is waiting to borrow it.

All items (other than Interlibrary Loans) will be automatically renewed for up to 2 years (due to Covid), unless requested by another user

If an item is requested you will receive a Recall email with a new due date.  A guide to borrowing with loan periods can be found at: http://library.aru.ac.uk/services/lending.htm
