The Turtledove Awards for 2012 were held in January and February 2013.
They introduced several new categories, particularly the Alternate History Features and the Robert P. Perkins Award for Outstanding Contributions to Alternate History (intended as a Hall of Fame-style award). The latter was set up in memoriam of robertp6165, who's untimely passing in early September 2012 shocked the AH.com community.
