The final stage, once a publisher has been found, is the transformation of the manuscript into the copy ready to be printed.
In the case of Odysseus, when my website was created, a draft was put on it, along with maps, some of which were animated, and during the year before it was printed I had made an audio recording of it that was also placed on the website.
At this stage, both the editor and I looked at it carefully, discovering very few errors. And then the book finally arrived.
