To me the difference between peer editing and peer review
is really - it's akin to
differences of types of reviews in publishing. So there are often
developmental editors
who work early on with a writer, and then you have copy editors at the end
who make sure that the commas are in the right place and at how style is being respected.
To me, a peer edit is that
Are the commas in the right place? Is the citation style good?
It's that sorta lower-level nuts-and-bolts stuff
whereas peer review is more like a developmental review in publishing.
It's that developmental editor working with the writer to get
a book to the place where it's ready for a copy editor
