A new version of my copyright duration chart, "Copyright Term and the Public Domain in the United States," is now available at <http://www.copyright.cornell.edu/training/Hirtle_Public_Domain.htm>. 

The chart began as an expanded version of Lolly Gasaway's copyright chart, but with the primary focus on unpublished works (though I included published as well).  In this new version, the section on unpublished works has been updated to reflect copyright status as of 1 January 2004.  A new section on the U.S. copyright status of works published outside of the U.S. has also been added.  In order to facilitate printing, a PDF version of the file is available as well, and several new alternative copyright charts are listed in footnote 1.

I welcome corrections or suggestions for improvements.
