Interlibrary Loans

ALA Library Fact Sheet 8

As defined by the Interlibrary Loan Code for the United States, "Interlibrary loan is the process by which a library requests material from, or supplies material to, another library. ... The purpose of interlibrary loan as defined by this code is to obtain, upon request of a library user, material not available in the user's local library."

This fact sheet has been designed for libraries in the U.S. and Canada. If you are outside of the U.S. and Canada, please see the section on international interlibrary loan below and follow the guidelines set forth by the International Federation of Library Associations (IFLA).

 

Interlibrary Loan in the United States

Libraries should follow the Interlibrary Loan Code for the United States, originally approved in 1917 and most recently revised by the Codes, Guidelines, and Technical Standards Committee of RUSA STARS (Sharing and Transforming Access to Resources section) in 2015.  Revisions were approved by the RUSA Board of Directors on January 11, 2016.  The ILL Code was also published in the Summer 2016 issue of the official RUSA journal, Reference & User Services Quarterly (v.55 no. 4, pp.306-307).  The Explanatory Supplement accompanies the U.S. ILL Code and is intended to amplify specific sections, providing fuller explanation and specific examples.

The U.S. ILL Code is intended to provide guidelines for exchanges between libraries in the United States when no other agreement applies.  The Code does not override individual, consortial, state, or regional agreements which may be more liberal or more prescriptive.  

Most state and regional library networks/consortia and state library agencies have interlibrary loan procedures, and libraries in their service areas should be familiar with these procedures.

 

Interlibrary Loan Form

Libraries normally transmit requests electronically through OCLC, DOCLINE, or other networks.  When an electronic means of making a request is unavailable, the ALA Interlibrary Loan Request Form (a fillable PDF) may be used. 

The form can also be purchased in bulk from library supply houses. A list of directories of library product suppliers is available on ALA Library Fact Sheet 9, Library Products and Services.

Interlibrary Loan in Canada

Loans to Canada are conducted on much the same basis as domestic loans, with slightly different mailing procedures (many Canadian libraries are part of OCLC or other networks).
