Library Services

Reference services are provided in person and via telephone, email, and live chat (found on our homepage).

While assistance to seminary students and faculty take priority over outside requests, we are always happy to help you!

Interlibrary Loan

Current GTS students, faculty, and staff may send requests to the Reference Librarian for items to be obtained from other libraries as loaned physical items or scans. Please note that some requests may take several weeks to arrive.

We are unfortunately unable to fulfill requests for GTS alumni or members of the public. In these cases, a local public library may be able to assist.

The Keller Library participates in several cooperative organizations that facilitate interlibrary loans. These are the American Theological Library Association (ATLA), New York Theological Library Association (NYATLA), New York Metropolitan Reference and Research Library Agency (METRO), and the Online Computer Library Center (OCLC).

Excluding Special Collections materials, we will loan material that is not too old or fragile to send. We do not lend materials published before 1920 or periodicals (bound or unbound).

There may be other, more efficient ways to obtain the material desired, so please plan ahead and consult with the Keller Library staff to determine which options best suit your needs.

Other Libraries in New York

GTS students who have registered with Union Theological Seminary may borrow materials from the Burke Library. Individuals who live or work in New York City may apply for a New York Public Library card. Ask the reference librarian for information about how to get direct access to other libraries.


Starting June 1st, the library will be reopened to the public. Visitors must be fully vaccinated and show proof at the front desk. Masks are not required for those who are fully vaccinated. Please keep the following guidelines in mind:

  • Maintain proper spacing at library tables 
  • Continue social distancing/don't crowd areas
  • Please wash your hands and use the hand sanitizer station by the library doors 

The library will close at 5pm on Thursday November 17th and at 1pm on Friday November 18th. We apologize for any inconvenience.
