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."
Thanks to a mix of statewide database subscriptions and legal collections of free materials, you may be able to find the item your patron wants at no cost as an electronic copy.
