Library items may be returned to any NCPL branch (Casper, Mills, Edgerton, Bookmobile). At the main library, drop boxes are located at the main checkout desk, as well as an outside book-drop on the east side of the library. Items returned in the book drop after the library closes will be credited as having been returned that business day.


Each library item may be renewed twice, unless another user has placed a hold on the item. Renewals can be done in person at any library branch or online in the My Account section (you will need your library card number and PIN). You may also renew materials 24-hours a day using our automated phone system at (307) 577-7323 ext. 4. You will be asked to provide your name, phone number and library card number (located on the back of your card), and specify which items are to be renewed. NOTE: Updates will be reflected on your library account within 1 business day.


Items returned late will incur overdue fees of 10 cents per item, per day, up to a maximum of $3 per item. You will be notified of overdue items by mail, e-mail, or text message, depending on what contact information you have provided us. To change how you are notified of overdue materials, please see a library staff member, visit My Account (you will need your library card number and PIN), or call (307) 577-7323.


When an item is 42 days overdue, a $10 late fee will be assessed and the account will be turned over to a collection agency.


You are responsible for all items checked out on your library card. Lost and damaged items will be billed at replacement cost plus a $5 processing fee. The parent or guardian signing a minor’s library card application form is responsible for all items checked out on the minor’s card, including any fees for lost or damaged items.
