ILL Policies and Guidelines
How long can I keep an ILL item?

Due dates for physical ILL items will vary from item to item. The due dates are set by the library that lends us the book. We can request a renewal, but it is not guaranteed. All physical materials are subject to recall by the lending library. 

What types of materials are other libraries willing to lend?

Libraries are generally willing to lend circulating materials such as books, audio-visual materials, music schores, and microforms. They will also supply scans of journal articles and book chapters. 

Can I borrow an item that is listed in the Yale Library Catalog?

If an item is owned by Yale Library, but currently unavailable to the requesting user it may be requested through interlibrary loan.

Can I borrow a textbook through ILL?

Textbooks are often in high demand and it may be difficult for Yale Library to find a library willing to lend a textbook. Since ILL loan periods are often short, it would be unlikely a textbook could be borrowed through ILL for an entire semester.

Can I borrow a new book through ILL?

Newly published materials can be difficult to borrow through interlibrary loan due to availability and lending library policies on new materials. Users can request materials to be purchased for the Yale Library collection via the Purchase Request Form.

Can I renew an ILL item?

Renewals can be requested, but are contingent on the lending library’s response, discretion, and policy.

Can I request an ILL item if I have overdue items, fines, or billed items?

Users with fines, billed items, or overdue items recorded on their circulation account will not be allowed to check out interlibrary loan items.

Where do I return my ILL items?
Physical ILL items may returned to any Yale Library or book-drop.

Warning of Copyright Restrictions

The copyright law of the United States (Title 17, U.S. Code) governs the making of photocopies or other reproductions of the copyright materials. Under certain conditions specified in the law, library and archives are authorized to furnish a photocopy or reproduction. One of these specified conditions is that the photocopy or reproduction is not to be “used for any purpose other than in private study, scholarship, or research.” If a user makes a request for, or later uses, a photocopy or reproduction for purposes in excess of “fair use,” that user may be liable for copyright infringement. The Yale University Library reserves the right to refuse to accept a copying order, if, in its judgement fulfillment of the order would involve violation of copyright law.
