Borrowing from Duke, NC State, and NC Central

What is TRLN?

TheTriangle Research Libraries Network (TRLN) is a collaborative organization of Libraries at Duke University, North Carolina Central University, North Carolina State University, and The University of North Carolina at Chapel Hill.

What is Interlibrary Borrowing?

Currently, faculty, students, and staff of TRLN institutions can use their institution’s search engine to search for resources across the coalition. For example, UNC students can use the UNC-Catalog to search for materials at nearby institutions. Requests are handled by the Interlibrary Loan offices at each campus.

Who is eligible?

Students, faculty, and staff who are currently affiliated with UNC-Chapel Hill (Academic Affairs) may submit interlibrary loan requests.

What can I borrow?

Circulating items and copies of journal articles can be requested through the TRLN Document Delivery Service. Media materials (DVDs, CDs, VHS), materials in Reference or on Reserve, materials that are “Library Use Only”, journal volumes/issues, and most materials held in Rare Book and Special Collections usually do not circulate.

You cannot request books used as required texts in current classes.

Note: Due to copyright restrictions, we cannot request more than one article from a single issue of a periodical published within the last 5 years. (If you have questions, email us at or phone us at(919) 962-1326.)

How do I submit a request?

Start your search at the catalog and locate an item of interest. View the full record by clicking on the hyperlinked title. If the material is eligible for document delivery, click on the “Request This Title” button found in the upper-right hand side of the screen. A new browser window will open.

Click “Go.” You will be prompted to log into your Carolina BLU account with your ONYEN and password. If you already have an account, and the item is not a journal, you will receive a TRLN Loan request form with the information about your item filled in. Review the request information and, if correct, click “Submit this Request.” To request articles, search for the journal title in the catalog. Then, click on “Submit this Request.” The TRLN copy request form will display with fields for article author, title, volume, year, pages, etc. Enter this information and click on “Submit this Request.” Put any additional information in the “Notes” field.

FIRST TIME USERS: If you do not have a Carolina BLU account, you need to complete the registration form. Once you have created your account RETURN to the Interlibrary page, and request your title again.

How long does it take?

Typically, requests from TRLN libraries will be filled within 2 business days.

What if the item can not be filled by TRLN libraries?

If your request cannot be filled through the TRLN Document Delivery Service, we will try to fill your request from another library. Materials from other libraries take longer, up to two or three weeks or more. Allow more time for unusual or specialized materials. Please enter a specific date on the “Not Wanter After” line on the request form.

Where do I pick up my material?

You may select a specific library as your pickup location on the Loan and Dissertation Request forms. Microforms, “Library Use Only”, and fragile materials can not be delivered to non-Davis Libraries, but must be picked up from or used in Davis. NOTE: during this trial period it will take 2 or more business days for your material to arrive at its destination.

When an item arrives you will be notified by email. You can pick up most items at the Circulation Desk of your pickup location whenever that Library is open.

We deliver articles electronically by default in PDF format. Log on to your ILB account; on the main menu, choose “Electronically Received Articles.” This will give you a list of all items that you have waiting to view or download.

How do I request a renewal?

Request a renewal through your Carolina BLU account. Renewals must be made by the day BEFORE the due date. The lending library sets the loan period and some libraries do not allow renewals.

Who do I contact if I have problems or questions?

Direct questions about the document delivery service to the Interlibrary Borrowing office – Monday-Friday, 9:00-4:30. Our office is in Davis Library, Room 115.  You can send email to or phone us at (919) 962-1326.
