Updated copyright term chart is available

[Peter Hirtle <pbh6@xxxxxxxxxxx>]

A new version of the copyright duration chart, "Copyright Term and 
the Public Domain in the United States," is now available at a new 
URL: http://www.copyright.cornell.edu/public_domain/.

The biggest change is that, at the request of a user, two new 
sections have been added.  The first is on published and unpublished 
sound recordings, and the second is on architectural works.  Other 
small changes have been made to clarify some of the problems other 
readers have identified.  In order to facilitate printing, a PDF 
version of the file is available as well.

As you can tell, the chart is a constant work in progress, and I 
welcome corrections or suggestions for improvements.
