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 firstname.lastname@example.org 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.
