When people hand me a proposal or manuscript for a non-fiction book and ask me for a publishing opinion, we’ll talk about a number of issues. But I have one chief diagnostic question. Almost anything and everything an author has to say flows from the answer to this question. It tells writers what kind of vocabulary and images to use, how long the piece should be, how to organize the material, what to leave in, what to take out, and even where to try to publish it.
