Today might have been the last real pass-through for the text. At this point we’re just trying to find rogue carriage breaks and misuse of a/an. Assuming a clean slate, we’re… running out of reasons why not to slap various extras onto it and hitting publish.
Fun thing I learned about tonight: the difference between left/right margins and gutter/outside margins. The latter is what you use when you’re prepping something for publishing: you have to mirror your text and make the gutter margin wider than the outside, because the gutter margin is where they bind the pages to the spine. If you make both margins equal, or don’t mirror the text, it looks weird on the physically printed page. And now you know!
