Short review: if you're writing a scholarly book (dissertation to print; monograph; edited volume; or textbook) then buy this and read it. It will answer more questions that you even know you have.
I'm working on a monograph and this volume was highly recommended to me by a colleague who has published 2 books. For a while I told myself, "oh, I can find all that online" but wow, am I glad I bought and read this instead! It cleared up many misperceptions and gave me much insight into the process.
The book is written as advice to authors but the most valuable content is its thorough exposition of the publishing process and especially how and why publishers work the way they do. It includes most of the requisite types of information that you would expect: the various types of publishers, the steps in the process, how submissions, reviews, and editing work, and so forth. It's well worth it for the clear exposition of those processes.
What was unexpected and made it much more valuable was the clear presentation of the publisher's point of view. What does it really cost to publish a book? What are the various goals of publishers? Why is it better to consider authors and publishers to be a team? If you have questions such as, "why are royalty percentages what they are?" or "how will my book be promoted?" or "will the publisher get rich at my expense?" this book will answer your questions simply and well. By clarifying all of that, I feel that it has saved me an enormous amount of speculation and worrying, and clarified the publisher relationship in a very helpful way.
The general tone is one of encouragement but honesty. It helped me realistically sort out some of the options, feel pretty good about the track I'm on, and rule out some other projects before wasting time on them. Your value may vary, but if even one of these areas hits home then it is well worth the investment to read.
And, by the way, it's published by Cambridge (not necessarily reflective of them) and in its 5th edition. That speaks to how we should all aspire as authors (to be represented by the best publishers and to need future editions) and demonstrates how Luey walks the walk as well as she explains it.
