When an item becomes one month overdue, a billing notice is sent to you stating the replacement fee. If the item is returned within one year, the replacement fee is waived.
Eligible Boulder Public Library items will automatically renew up to three times if there is not another patron waiting for the item with a pending hold. Items from other libraries will automatically renew as well, but follow the owning library’s renewal policy. Check on the renewal status of your items in person, by accessing your account online, or by telephoning 303-441-3100.

- First overdue notice is sent after 7 days.
- Second overdue notice is sent after 14 days.
- A bill for material replacement is sent at 21 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.
