I think the last substantive revisions are done. Left to do:
- Write a paragraph of acknowledgments at the end of the preface.
- Check the last two chapters, the last ones that I haven’t yet, for awkward phrasing (such as unnecessary, the stuff you don’t need, parenthetical comments).
- Check references against the text.
- Complete the marketing questionnaire for the publisher.
Then it’s time to upload the manuscript and questionnaire.
