Copyright Compliance

Users of the University Libraries’ Interlibrary Loan and Document Delivery service accept responsibility for complying with United States Copyright Law.

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 reproductions. One of these specific 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 requests or uses a photocopy or reproduction for purposes in excess of "fair use," that user may be liable for copyright infringement. A library or archive may refuse to accept a copying order if, in its judgment, fulfillment of the order would involve a violation of copyright law.
