CONTU (National Commission on New Technological Uses of Copyrighted Works) guidelines apply only to materials less than five years old. Its provisions include:
Requests that exceed the "rule of five" may incur additional copyright fees. ILL staff will determine the price of additional article(s), and send the request to the Copyright Clearance Center for fulfillment. In some cases, the patron may be asked to cover additional costs to reproduce the material beyond a standard ILL request.
Before sending out an article, staff must check that the publisher's license allows transmission and sharing via ILL. Many of our databases allow articles to be sent via this method to patrons at other libraries, provided that a copyright notice is attached.
Patrons are advised that while ILL staff try their best to obtain materials from libraries' electronic holdings, sometimes licensing agreements prohibit the owning libraries from sending the article. In the event that we cannot find a library authorized to lend, we will cancel the request and advise you of further options.
