Eligible Items that Can Be Obtained

Books, book chapters, journal articles, conference papers, technical reports, theses, DVDs, CDs, VHS, and audiocassettes are all available for request. While technical reports and textbooks are eligible, they can be difficult to obtain. The Library will help to locate lenders for these items. However, if a lender cannot be found, then the Library will provide information, when available, on how the requestor may purchase the item using lab funds.

Supplementary Material/Data If there is any supplementary material (or data) that accompanies an article that would like to be requested, enter the information in the comments section of the request.

Delivery & Due Date

Delivery Method: You will receive an email letting you know when an article is available for download. You can access it from your ILL account via "Available to view." You can view or download the PDF up to five times. For loans of materials, you will receive an email notifying you that the item is available for pick up at your preferred pick up location, either Main [Bldg 1, Rm 1200] or Branch [DSRC 2C407] Libraries.

Average Delivery Time: Libraries usually deliver an article copy request within one to two workdays. Depending on the lending library and item availability, a loan request may take from three to seven days.

Rush Request: If you need an item by a specific date within 30 days, or if you need an item urgently, please submit your request, with a message in the Comments box, "Need by date", and contact a Library staff member at or (303) 351-2301.

Due Date: The due date is printed on the item's label. Most libraries allow one renewal. Many university libraries allow for three months use with no renewals.


Incorrect/Poor Quality PDF: If a PDF is illegible, missing pages, or the wrong item, contact Library staff as soon as possible. In order to ensure you receive your article copy as quickly as possible, our system settings enable most lending libraries to send the item directly to you. Boulder Labs Library rarely views the document before you are notified.

Lost/Damaged ILL Material: The lending library may require a replacement if an item is damaged. If an item is lost, the Boulder Labs Library will ask that you to find a replacement copy.

Compliance with U.S. Copyright Law

The copyright law of the United States (Title 17, United States Code) governs the making of photocopies or other reproductions of copyrighted materials. Under certain conditions specified in the law, libraries and archives are authorized to furnish a photocopy or other reproduction. One of these specified conditions is that the photocopy or reproduction is not to be "used for any purpose other than private study, scholarship, or research" (fair use). If a user makes a request for, or later uses, a photocopy or reproduction for purposes in excess of "fair use," that user may be liable for copyright infringement. Boulder Labs Library reserves the right to refuse to accept a copying order if, in its judgment, fulfillment of the order would involve violation of copyright law.

Thank you for following these procedures; they will ensure that you receive the best possible service.
