The Copyright Law of the United States (Title 17, United States Code) governs the making of photocopies or other reproductions of copyrighted material.
Under certain conditions specified in the law, libraries and archives are authorized to furnish a photocopy or other reproduction. One of these specified conditions is that the photocopy or reproduction is not to be "used for any purpose other than private study, scholarship, or research." If a user makes a request for, or later uses, a photocopy or reproduction for purposes in excess of "fair use," that user may be liable for copyright infringement. This institution reserves the right to refuse to accept a copying order if, in its judgment, fulfillment of the order would involve violation of copyright law.
CONTU Guidelines limit the number of requests a Library can make in a calendar year to no more than 5 request from a journal title for articles newer than 5 years old - without gaining copyright permission and paying copyright fees. Restrictions also limit requests to 1 article per issue per year without gaining permission and paying copyright fees (or 1 chapter for books or ebooks). Exceptions are Open Access journals and non-copyrighted materials like Government publications.
