It would be interesting to see just how much editing / correcting was
done on this manuscript. <snip>

Carol responds:

Almost certainly the manuscript received what is referred to in the
publishing business as a "light edit": Grammar, punctuation, spelling,
minor consistency matters that can be corrected by referring to a
style sheet, and in the U.S., Americanization of spelling,
punctuation, and a few terms that might be misinterpreted by readers. 

Here's one company's definitions of "light edit," "medium edit, and
"heavy edit," which are consistent with those of the various
publishers I've worked with:

(The part about figures and tables does not, of course, apply to a
fiction manuscript, but the U.S. copyeditor probably included
typecodes for the illustrations at the head of each chapter.)

If the editor in charge tells the copyeditor to do a light edit and he
or she does a medium edit, the copyeditor will get a reprimand or even
a warning. (Do this again and you'll lose your job.) If he or she is
told to do a light edit and does a heavy edit, he or she will almost
certainly be fired. Like Snape following Dumbledore's orders, you do
what you're instructed even if you don't like it.
