[pd-discuss] New article on PD in the US

[Peter B. Hirtle]

FYI, I have a new article out on how difficult it is to determine public domain status in the US that some of you may find interesting.  See "When Is 1923 Going to Arrive and Other Complications of the U.S. Public Domain<http://www.infotoday.com/searcher/sep12/Hirtle--When-Is-1923-Going-to-Arrive-and-Other-Complications-of-the-U.S.-Public-Domain.shtml>," Searcher: The Magazine for Database Professionals 20:7 (September, 2012). (http://www.infotoday.com/searcher/sep12/Hirtle--When-Is-1923-Going-to-Arrive-and-Other-Complications-of-the-U.S.-Public-Domain.shtml)

Best,
Peter Hirtle
