Section 108 of U.S. Copyright Law provides libraries and archives specific exemptions to the exclusive rights of copyright owners. These exemptions complement fair use in copyright law's intent to maintain the balance of the private interests of copyright owners with the public's interest in advancing the "progress of science and the useful arts". They assure in some measure that copyright-protected information is accessible to individuals for private study.
Section 108: Limitations on Exclusive Rights: Reproduction by Libraries and Archives permits libraries and archives to reproduce work if it is for "private study, scholarship, or research".
