Really helpful reference tool, packed with information for authors and publishers: capitalization, punctuation, abbreviations, lists of common words/phrases, US vs. UK differences, setting scripture references, Bible translations, institutional preferences, examples of typography variations, and other style conventions. Gives helpful context for certain vocabulary words, offers general guidelines to authors, describes copyeditor's marks, establishes expectations for obtaining permissions, and explains LoC copyright requirements/conventions. The writing has some wry humor in places, which made for an enjoyable read.
Much of the information can be found in other style guides, but what I most appreciated was a frame of reference for what's "usually" done, in Christian publishing. In many entries, the writer will present several different ways of doing things, but will end with some context or advice that nudges you in a certain direction--a comment like "this is how it's usually done" and such. This is really helpful for deciding how to style something that isn't "wrong" either way, but you want to know how other people tend to do it, so you can be in line with the industry.
My only critique is that, at one point, the writer describes what an "editor" does, only describing the tasks of an acquisitions/commissioning editor at a publishing house. I can think of at least 7 different types of "editing" in the industry, and (if he's going to do an entry for this anyway) he should have taken the time to name and describe all types of editors (i.e. acquisitions editing, developmental editing, content editing, line editing, copyediting, proofreading, production editor, etc.).
Okay, a second critique, is that many elements which the writer pointed out as being true of Roman Catholic and Anglican worship/culture are also true of Lutheran culture. He's stronger on his knowledge of RC and American Evangelical cultures than he is of other traditions. Also, I wish more details about various Mennonite traditions had been included.
I read the 2004 edition, which has some outdated pieces. Still talks about paper manuscripts, CDs, old file requirements, and such. (I'm a millennial, and I've used a floppy disk, but what's a Zip disk?)
