Is It in the Public Domain? Duration, Restoration, Formalities, and How to Actually Tell
By Casey Scott McKay ·
Whether a work is in the public domain is a question of arithmetic and formalities, and getting it wrong costs a client the entire economics of a project. This article works the determination in the order it should be done - what the work is, when it was published, whether notice and renewal were satisfied, and whether restoration revived it. It explains the pre-1978 renewal system that stranded most works of that era, the 1978 and 1989 boundaries that ended formalities, and why Golan v. Holder means a work in the public domain for decades can be protected again. It covers the derivative work layers that make a public domain source unusable in the form the client has, the separate treatment of sound recordings and government edicts, and the risk memorandum that a clearance actually produces.
