Instructions and Frequently Asked Questions
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:
- Book chapters (as pdf files)
- Journal articles (as pdf files)
- 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.
