Upon a procedural review, SFWA discovered an error in the final Nebula Awards tally. Two works that should be on the final ballot were not listed: the novelette "The Ray_Gun: A Love Story" - James Alan Gardner (Asimov's, Feb08) and "Mars: A Traveler's Guide" - Ruth Nestvold (F&SF, Jan08) in short stories. No other changes have been made to the final ballot. We apologize for the error and have made changes to the procedures to keep this sort of mistake from happening again. The updated final Nebula Awards ballot is available at Posted March 2, 2009
