Patrick Nielsen Hayden corrected me on Beth Meacham’s edited books for the year. The correction is now live here. Thanks, Patrick!
If anyone has more corrections, please let me know. In fact, if someone can help me Ginjer Buchanan’s edited books I would be very grateful—that’s the last piece of missing information I have for the Hugo 2008 Countdown.
Update: Ginjer was on vacation, but Cameron Dufty was kind enough to give me three for now. Fortunately I did get two of the books right—Halting State and Galactic North. Thanks, Cameron!
