A note on charges: CU no longer charges overdue fines, but continues to charge fees for recalls, lost books, and damaged books. Fees for books borrowed using CLS or ILL may differ.
We thank those who return borrowed items as soon as possible and make them available to other students and faculty.
*Graduating students who have outstanding loans at the time of graduation will have a hold placed on their library account and be unable to obtain a transcript until their library account is settled.
Are the library stacks open for browsing?
All patrons may browse our SearchBox catalog online using the Virtual Browse feature. To see this, search for a book in our collection and click on the title, then scroll down to the bottom of the catalog entry to find the Virtual Browse section.
How do I check out library items?
Patrons in the library may borrow books by using the self-checkout machine located in the first floor lobby, or by stopping at the Circulation Desk, where a staff member will charge out the item for you.
You may also request a book for pickup through SearchBox. Staff will pull the item, charge it out to you, and email you that the item is ready to be picked up and circulated.
Am I able to request items owned by other universities, using CLS or ILL Delivery?
Yes, both physical items and online items are being delivered.
Physical Items -- note: expect some delays.
Consortium (CLS) and InterLibrary (ILL) lending of physical items has resumed. However, many libraries are still closed. You may experience longer waits and we may be unable to fill some requests.
The InterLibrary Loan service is continuing to request materials which can be delivered electronically. Please submit your requests for electronic versions of book chapters and articles by logging in to your ILL account.
FAQs about textbooks and course readings
Is it okay to upload my own scan of a library item to Blackboard?
No, usually not. The library needs to manage these uploads in our course reserve system for two reasons:
When library staff upload to course reserves, we make sure fair use standards are being followed.
The library tracks usage of library items on course reserve. This data informs our decisions about subscription renewals and cancellations. Direct faculty uploads to Blackboard do not offer library usage data.
Can I put books on Course Reserve for my class?
Yes and no. Course reserves for physical items are suspended for the summer 2021 semester for the below reasons. We cannot reserve physical copies of items owned by the libraries or you personally.
Because many students will be taking all or some classes online, we need to ensure that everyone has access to resources online.
Online access to course materials allows flexibility for any individual, university or regional contingencies related to COVID-19.
Please speak with your liaison librarian about other options. We may be able to purchase the title as an e-book, or we may scan a portion of a physical book in our collection (within copyright guidelines) that can be linked for your Blackboard class.
Can Mullen Library staff scan course readings for my class?
Yes, within copyright guidelines. Faculty can request that library scan course texts and upload them through our online course reserves. The library can scan chapters in library-owned books, instructor-owned personal books, and other readings. Instructions are below.
How to have us scan your readings (for instructors):
Once the scan is completed, we will email a link to the resource. The link can then be put into a Blackboard course.
Things to note
We can scan a chapter, or up to 10% of a volume, but we cannot scan entire textbooks because of copyright law.
If you wish to scan from a personal copy, please email email@example.com to schedule a drop-off. We will let you know when your copy is ready to be picked up.
Library staff will check for ebooks and online availability before scanning texts. If the resource is already available, we will let you know how to have your class access it, rather than creating a new scan.
Do we have access to online textbooks?
YES, to many textbooks. We suggest these options:
The Open Textbook Network has freely available e-books that may serve as an alternative to an assigned textbook reading. Their offerings are arranged by subject on the Open Textbook Library website at https://open.umn.edu/opentextbooks. All books and teaching materials offered through the Open Textbook Network are always available for free.
The University Libraries has a limited number of e-textbooks in our collections, but it is always a good idea to check SearchBox.
If you would like to learn more about online textbooks and open educational resources (OER), our OER guide has all the information along with liaison-recommended open textbooks.
