Interlibrary loan activities must follow the guidelines of CONTU, which refers to the Commission on New Technological Uses of Copyright Works.
For materials less than five years old, up to five articles may be requested from a single periodical within a calendar year. This is referred to as the "rule of five." Be sure to keep this in mind if planning to request multiple articles from a single periodical.
No more than six copies of articles/chapters/small portions may be made from a non-periodical (such as a book) during the entire term of copyright of the work.
Interlibrary Loan is a cooperative agreement among libraries that allow libraries to borrow materials from each other for the benefit of their library users. Copyright guidelines govern the types of copyring and loaning libraries participating in ILL agreements can do. For more information, please visit.
