Subject: Updated PP4 and Updated Implementation Readings From: "William J. Rapaport" Date: Tue, 23 Mar 2010 11:33:26 -0400 (EDT) As previously noted, I have corrected an error on Position Paper #4; the corrected version is now online. Also, my required reading on implementation (Rapaport 1999) doesn't print, for some reason. Fortunately (for you), that was the "longer" version. So I've replaced it with the shorter, published version. Go to the Readings to access the corrected link.
