Statutory Law

• Federal copyright law is contained within Title 17 of the United States Code, which is available from the Government Publishing Office website or in print. The United States Copyright Office also provides a publication that contains the text of Title 17 and other useful information on copyright law. 
• Title 17, Section 108 of the United States Code directly references libraries and archives, including issues such as patrons making copies of library materials.
• State law on copyright is preempted by federal copyright law. However, some state laws may still be important to consider. For example, in South Carolina you can find statutes describing prohibitions against, and punishments for, the creation of "Bootleg and Counterfeit Records, Tapes, and Recordings." These statutes are located at Title 16, Chapter 11, Article 9 in the South Carolina Code of Laws.
