Oops! You may be right, Erosiaart. The magazine publishing house where I used to work also published books. Fancy Publications had something like 40-50 magazines and a book division all in one building, and I worked in the electronic/art department, not in the editorial department, so I was not an editor in this case. Perhaps the book division is where I saw the galley proofs, which I think are pretty standard for books. The magazines typically came back from the printer as Rainbow proofs and bluelines, which the production coordinators and editors would look over for a final proofing, and I might have gotten them confused with galley proofs. Sorry for the confusion! :)
