Borrowing from Duke, NC State, and NC Central

What is TRLN Direct?

The Triangle 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. TRLN Direct is the service used to borrow and lend materials across the consortium.  

What can I borrow?

Circulating items can be requested through TRLN Direct. 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. 

Books used as required texts in current classes may not be requested. 

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  

How do I submit a request?

Start your search at the shared catalog and locate an item of interest. View the full record by clicking on the title. If the material is eligible, click the “Request” button.  

You will be prompted to log into your Interlibrary Loan & Carolina BLU account, which will open a request form with some of the information about your item filled in.  

FIRST TIME USERS: If you do not have an account, you will first need to complete the registration form. Once you have created your account, return to the request page, and request your title again. 

How long does it take?

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

What if the item cannot be filled by TRLN libraries?

If your request cannot be filled through TRLN Direct, 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 Wanted After” line on the request form. 

Where do I pick up my material?

You may select a specific library as your pickup location. Microforms, Library Use Only, and fragile materials must be picked up from or used in Davis.  

You will be notified by email when an item arrives. You can pick up most items at the service desk of your pickup location whenever that library is open. 

How do I request a renewal?

Request a renewal in My Library. Renewals must be made by the day before the due date.
