"What does Best Book mean in the context of a sung-through show? I've wondered this for a long time and have been trying to google it but failing."
A book-writer's job is not just to write the words, but also to structure the show - deciding what plot elements to include, what order they go in, when to bring them back, deciding which characters should be in the show, and how they are written, etc. In this case, Lin-Manuel did all of these things through the lyrics/music, but he still did the job of a book-writer, in the ways I mentioned above (and did a damn good job of it, I might add)
I'm sure others could expand on what I said, but I think that's the basic gist of it.
