Jeff Nyman recently raised the idea of having a guide to Inform 7 specifically written for an experienced fiction author without background in IF, and I posted a brainstormed outline for such a project. The formatting was pretty ugly on Usenet, though, and I had a few ideas for revisions, so here is another, longer and better-laid-out version of the same thing, with more links to relevant games and articles.
This still isn’t nearly into the shape I would use if I were actually going to write this book — and I don’t have time to do any such thing right now anyway; I have a bunch of things to do for Inform 7, feelies.org, and the long-neglected theory book before I could take up a project of this magnitude. (And I’d like to have a little time to work on a WIP of my own — IF support work has pretty much wiped out my time for that kind of thing lately.) But possibly people will find the brainstorming interesting, even if it isn’t worked up into a complete document.
