About The Digital Millennium Copyright Act

Legislative history, scope, definitions, and the relationship between this measure and existing federal law.

Purpose and legal framework

The DMCA is broader than takedowns. Its five titles implemented international copyright treaties, created online liability limitations, added a computer-maintenance exemption, made miscellaneous copyright changes, and protected certain vessel-hull designs.

The notice-and-takedown system is found in 17 U.S.C. § 512. Anti-circumvention rules are found in § 1201, and copyright-management information protections in § 1202.
