What does "Request Item" mean in the library catalog?
The "Request Item" button is for placing copies of checked-out books on hold when they are returned to the library.
When you click "Request Item" in the library catalog and enter your account information, that item's checkout will not be renewed. When it is returned to the library, you will be contacted and the item will be held for you at the circulation desk for 3 days.
If a book is not checked out, requesting it has no effect.
