What is Public Domain?
Public Domain (often abbreviated, "PD") is a body of intellectual material which is not under copyright and may be used without permission. This includes:
- Works which the owner has explicitly moved into the public domain
- Works in which copyright has expired
- Works in which copyright has lapsed due to failure comply with necessary formalities such as renewal and notice
- Works created by the United States Government (see 17 U.S.C. §105), as well as the works of many state and local governments.
