The Digital Millennium Copyright Act of 1998 amended several areas of the U.S. copyright law law including Section 108, "Limitations on Exclusive Rights: Reproduction by Libraries and Archives." Section 108 of the copyright law allows libraries and archives to reproduce and distribute one copy of a work under certain circumstances. For example, libraries may photocopy journal articles, book chapters, etc. and send these copies to other libraries through interlibrary loan.

The library may also make up to three digital copies to replace a work in an obsolete format as long as that format is not made available to the public outside of the library or archives.
The library or archives may reproduce, distribute, display, or perform in facsimile or digital form ant work in the last 20 years of its copyright term for purposes of preservation, research or scholarship. This change to Section 108 was made to address the concerns of libraries and non-profit educational institutions planning to reproduce and distribute materials that would have fallen into the public domain if the copyright term extension act had not been passed. This means that, although the term of copyright has been extended by 20 years, libraries may copy or digitize works that are in the last 20 years of their copyright term. In order to take advantage of this exemption, however, libraries should make a reasonable effort to determine that:
