24 hours before a title is set to return, a renew button will appear below the item when you are logged in to your hoopla account:
You can renew as many times as you have borrows remaining, and you do not need to re-download the item. Please note that a renewal is the same as a new borrow, so a renewed title will count against your monthly limit. After renewing, your title will remain on your device for another borrowing period.
Due to record label restrictions, music albums can be checked out only twice per month, including renewals.
