Quick View

What is it?
Interlibrary loan is a delivery service that can be used to obtain academic materials not available at Yale from libraries around the world.

When do I use it?

If a book, article, dissertation, or other item is not available anywhere at Yale then you should place an ILL request. Items on reserve or in non-circulating collections are considered available at Yale.

Who can use it?
ILL is limited to current students, faculty, staff, fellows, post-docs, and alumni who have purchased library privileges.

How long does it take?
ILL turnaround times depend on availability and are highly variable. Most requests take two to three weeks.

How long can I keep materials?
Lending times are determined by the lending library. Renewals cannot be completed online and must be requested by emailing more than 1 week before the due date. Items may be due sooner if recalled by the lending library.

What is an ILL account?
ILL requests are maintained outside of ORBIS. All ILL transactions are processed through this ILL account. Although an ILL account can be created for users without a netID, most Yale patrons will use CAS to sign in.


Interlibrary Loan Overview

Interlibrary Loan (ILL) is a service that allows Yale patrons to request library materials from institutions all over the world. If a book, journal, dissertation, or other item is not available in the Yale library system or through Borrow Direct then the ILL department will attempt to obtain it from a global network of partner libraries. Interlibrary loan requests should be made online using the online request form. First time users should check the ILL step-by-step guide. Non-Yale patrons and libraries should check the FAQs for Yale's ILL lending policies.ILL is usually used to fulfill requests for certain formats:

  • Books
  • Book chapters (as pdf files)
  • Journal articles (as pdf files)
  • Microfilm/Microfiche
  • Dissertations and theses
  • Conference proceedings

Some items can be difficult to obtain through ILL. These include:

  • Rare and pre-1850 books and manuscripts
  • Popular fiction
  • Entire journal volumes
  • Films and audio recordings
  • International dissertations

Some items may not be requested through ILL:

  • Items available at Yale, even in non-circulating collections
  • Textbooks in use at Yale (even if checked out of the library)
  • Materials on reserve at any Yale library

Turnaround times are highly variable and depend on the availability of materials and circulation policies.
