How Long Is Your Copyright Valid?

Mine!

Panzer was wondering how long a copyright is in force.  He wanted to know exactly how long he'll own the copyright on Cats and Crime.

Well, my bad boy did some searching around in the Catosphere. He found a paper prepared by Cornell University with just the information he was curious about. Not only does it have the length of copyright for published work, unpublished work, music, etc. (sorry this is for the U.S.A.); but it's a downloadable pdf document.
