In the past couple of months I’ve worked on editorial letters from two editors/houses. I’ve worked with four editors so far, and each has a different approach. Here are the most recent:
1. Publishing House 1: Overview of things that need to be worked on, in order of importance. That took 2-3 pages. The rest gave page numbers and notes on what the particular issue was on that page. Its focus was mostly on what needed to be fixed.
2. Publishing House 2: Brief overview, followed by discussions of the market, structure, setting, timeline, points of view, plot, themes, and queries/margin notes. While this letter was as long as the first, it actually contained a lot of compliments as well as observations, so the amount of work it contains was less.
