Borrowing Privileges:
      Friends of the Libraries Gold Membership

With some exceptions, library materials may be used within the library by anyone. If you wish to take items outside the library, you must apply for borrowing privileges.


To apply for library privileges through the Friends of the Libraries, please contact their office.  The Friends will work with the Libraries to set up your account.  You will need to stop by the Circulation Desk at the main library (Norlin) on your first visit in order to activate your account.


Once registered, your driver's license or any photo ID will serve as your library card. You must present your photo ID every time you check out library materials. Your library privileges are valid for one year. Friends in good standing may renew their privileges on a year-by-year basis.

Books circulate to Friends (Gold Membership) for 90 days with the exception of short-period loan items. Friends (Gold Membership) may have up to 50 items checked out on their account. A maximum of five Reserve items may be borrowed simultaneously.

"My Chinook," a feature located on the Chinook Catalog main page, serves as an access point to your library account. In My Chinook, you may renew your own books, place or cancel holds, create preferred searches, and use other Chinook services. You will need a PIN Code in order to use this program.


If you do not currently have a PIN, leave the PIN field blank and submit your request. You will then be asked to create your own PIN.


If you should forget your PIN number, have problems creating one, or your PIN does not work, please come to the Circulation Desk in Norlin Library and bring your picture ID. Even though we cannot see your existing PIN number, we can delete it for you so that you can then create a new one. Some circulation desks in branch libraries can also do this.

Books may be renewed an unlimited number of times for an additional 90 days each time

in person at the Circulation desk, or


by phone at 303-492-7477, or


by e-mail at norcirc@colorado.edu.

Patrons may renew their own books by using the My Chinook option in Chinook. However, if a recall has been placed on a title by another patron, the item may not be renewed.


A receipt is printed for all books checked out at one time, indicating the due date for each item. These dates may vary with item type. There are NO FINES for most materials. Reserves, recalled books, and some special collections such as those housed in the Media library will still generate fines. Should you be billed for an item and later return it, there is a non-refundable service charge of $10.00 per item. Various notices will be sent out reminding you to renew or return your books before a bill is generated.


Email is the preferred method of communication, though for Public (non University) patrons ONLY, we will send notices by regular mail if an email address is not provided. Please note, however, that courtesy notices (sent out 3 days before items are due, alerting you to the fact that your books will be due soon) are sent only for those patrons who have provided us with an email address.

If a book is checked out to another patron, you may request that the Circulation staff place a recall (advance the due date of the item and notify you when it is returned). If the book is due in more than two weeks, the due date is changed to 10 days from the time the recall was placed. When the item is returned, a notice is e-mailed to you indicating that it is available for pickup. You may also initiate a recall through Chinook by using the Recall/Hold button.


If a book checked out to you is requested by another borrower, you will be notified by e-mail of the adjusted due date. This new due date is the latest that you can return materials before your library account is blocked and recalled fines begin to accumulate . As long as there is a recall on the book you cannot renew it.

Circulation privileges will be revoked for anyone who has one or more overdue recalled books, or one or more billed items. Charges for books assumed lost and/or overdue fines will be referred to a collection agency as required by Colorado State Law, if unpaid 30 days after the bill due date.

Items assumed lost (90 days overdue in most cases; 30 days for short term checkouts such as bound journals) are billed for replacement at the following rates:


Books $200.00
Government Information $ 50.00


If the item is returned, the replacement fee is waived and library privileges are automatically reinstated, but effective July 1, 2005, there will be non-refundable $10.00 service charge per item, to cover our billing costs.

During library hours, please return books to the appropriate library. After hours, you may use the outside book drops. We encourage patrons to obtain receipts for books returned to UCB Libraries.


We discourage returning our books to non-UCB Libraries as you may be held responsible if the book does not reach us.
