Digital Millennium Copyright Act (DMCA)

What is the Digital Millennium Copyright Act (DMCA)?

The Digital Millennium Copyright Act (DMCA) of 1998 is an amendment to U.S. copyright law that attempts to address copyright issues related the new and emerging technologies of the Digital Age (i.e., the Internet) that were not represented in previous legislation. The DMCA brings U.S. copyright law into compliance with World Intellectual Property Organization (WIPO) Copyright Treaty and the WIPO Performances Phonograms Treaty. Additionally, the DMCA:

  • Enables copyright holders the ability to limit access to copyrighted digital works;
  • Prohibits the circumvention of technological protection measures (TPMs) of copyrighted works;
  • Prohibits the removal or alteration of copyright management information;
  • Limits the copyright infringement liability of online service providers (OSPs);
  • Allows temporary copies of software to be made for repair purposes; and
  • Permits libraries to make digital copies of copyrighted works for replacement or preservation purposes as well as "loan" these copies to other institutions.

DMCA Exemptions

What are the Exemptions to the DMCA?

Section 1201 of the U.S. copyright law enables the Librarian of Congress to review the general prohibition against prohibition against circumvention of technological measures protecting copyrighted works and determine if some classes of material should be exempted from this rule. Rulemakings of these exemptions are released every three years.
