Due Date & Overdue Notification
Knowing when your library items are due is your responsibility. There is no grace period. To help you keep track of item due dates, the library sends the following notices:Three day advanced courtesy e-mail notice.
- First overdue notice is sent after 7 days.
- Second overdue notice is sent after 14 days.
- Third overdue notice is sent after 21 days.
- A bill for material replacement is sent at 30 days.
Be aware that non-receipt of these notices does not release you from your responsibility to return materials on time. It is your responsibility to let us know when your mailing address, telephone number or e-mail address has changed. You must have a valid e-mail address in your library account in order to receive courtesy notices. If you do not provide us with an e-mail address, the one-week and two-week overdue notices will be provided to you by telephone. The bill for replacement charges (sent after items are three weeks overdue) is always mailed to you. To update your e-mail address, call 303-441-3100 or log on to your account. Library accounts with items that become five weeks overdue may be sent to a collection agency.
Paying Fees & Blocks on Your Card
You may pay any fees with cash or personal check at the check-out desk at any library location. You may make credit card payments at the Main Library or online at https://nell.boulderlibrary.org/patroninfo. Note that any fees totaling more than $10.00 will block your borrowing and renewal privileges.
Your borrowing, renewal, and database access privileges are blocked if:
- you have 1 or more overdue library items that have holds, or
- you have 1 or more library items that are 15 days overdue, or
- more than $10.00 in fees owed (see payment information), or
- your account has expired.
Lost and Damaged Items
When library items become three weeks overdue, a billing notice is sent stating the replacement fee. This fee must be paid if the item has been lost. If the Library item is returned, late fees are charged and the replacement fee is waived from your account.
Replacement fee = Library’s cost of the item + $5.00 processing fee
Books in a Bag and NOOKs have a separate replacement fee structure.
The replacement charge for ANY materials borrowed from a Prospector library is $40.00, no exceptions.
The Library is UNABLE to accept replacement items in exchange for any lost materials or refund the replacement fee should you locate the material at a later date.
The Library charges to replace missing parts or to repair or replace damaged library items. Extreme heat or direct sunlight may harm audio-visual library items. You are responsible for paying replacement charges for any materials that are damaged while checked out on your library account.
The replacement fee for items with damaged or missing parts is $15.00 for items belonging to the Library (see exceptions for Books in a Bag and NOOKs) and $40.00 for items belonging to any Prospector library. The replacement fee will be waived if all parts are returned, though late fees may still apply. Ask a library staff member for specific replacement fees for damaged library materials.
The Library assumes no liability for the use of audio-visual library items, including but not limited to CDs, DVDs, and videos or for the equipment on which these items are played.
If an audio-visual item that you have borrowed malfunctions or has sustained damage by the previous user, please notify a library staff member so it can be repaired or replaced.
