Clearing a Work for Public Domain Use: A Practitioner's Guide to Duration Analysis, Renewal Research, Restoration, and Risk Documentation
By Casey Scott McKay ·
This guide clears a work for use, producing a memorandum rather than an answer, in the order the research should be done. It starts with identifying the specific artifact and its layers, because most errors are identification errors rather than arithmetic ones. It works the publication determination, the notice examination on a first-edition copy, and the renewal search protocol including how to document a negative result so it is worth something. It then runs the restoration analysis that reverses the answer for foreign works, the unpublished branch with its own term structure, and the separate sound recording regime. It covers orphan work searches as risk mitigation rather than defence, the trademark and publicity overlay that narrows the permission, and the six-part memorandum that is the actual deliverable.
