I got the proof for A Dislocated World last night, and sure enough there were things that needed fixing that were not apparent in my printouts. I also went through the interior layout and index and made a couple of fixes there. (I’ll order a second proof once this is all uploaded.)
I didn’t sleep well last night, and I did the edit this morning before any caffeine, when I was at Peak Grumpiness. This often does help my copy editing (as long as I’m not actually too tired to function or care), and it’s why I think it was probably a good thing I never actually worked in an office as a copy editor—to be at Peak Effectiveness, it often helps for me to be at Peak You-Don’t-Want-Me-As-Your-Co-Worker.
