The UNC Libraries are members of a local consortium of libraries known as the Triangle Research Library Network or TRLN.

The TRLN includes the libraries of Duke University, North Carolina Central University and North Carolina State University.

The collections of each of these libraries can be searched through their individual library catalogs. All currently enrolled students, faculty, and staff can use their UNC One Cards to check out books and other materials.

Duke University's Perkins Library is particularly convenient to physical access thanks to the Robertson Scholars Express Bus service which runs directly from the UNC campus to the Duke campus.
