About interlibrary loan

What is interlibrary loan (ILL)?

  • Interlibrary loan is a service which provides you with study and research materials not available in the Coates Library. We borrow books, DVDs, and CDs for you from other libraries and deliver electronic versions of journal articles and book chapters to your desktop. The conditions of this service are set by local agreements, the regulations of the individual lending libraries, and the National Interlibrary Loan Code.
  • The Coates Library uses an ILL platform called ILLiad to manage your requests.
Who may use ILL?  

  • Current Trinity University students, faculty, retired faculty, and staff in good standing are eligible. 
  • Coates Library covers the cost of ILL services for students. 
  • Coates Library subsidizes the cost of ILL services for faculty members up to $500 per faculty member per fiscal year.  We ask that the academic department cover fees that exceed $500. 
  • If your borrowing privileges have been blocked, we cannot supply interlibrary loan services to you. However, as soon as you take the needed steps to restore your good standing, we will be happy to fulfill your requests. To discuss your status, please contact Jason Hardin, Head of Access Services (, 8181).
