Steph, it is pretty much a "behind the scenes" kind of thing. Most people don't think about why a type style is used or who chooses the artwork/photos to include in a book. In fact, I don't generally notice that the person responsible is credited. More often, I see a credit for the cover design, not the whole book. Anyway, for the most part, the format regarding what goes in what order in a book has been pretty much standardized. I have noticed that publishers are putting acknowledgments near the end of the book instead of with the front matter. These books don't have a forward or intro by the author, translator or editor. It's just something I've noticed lately, but it could be that I am just paying more attention now-a-days.
