Most resources (excluding reserves or high demand items) can be renewed twice, each for an additional three week period as long as no one has placed a hold on the item. After you have renewed your library materials twice, they must be returned and sit on the shelves for a full day before you can borrow them again.
There are three ways to renew items.
If you are unable to renew your materials you have either exceeded your allotment (twice per item), or the item is on hold by another user. Please read any warning messages clearly and contact library staff if you are unsure of how to proceed.
