*** Revision & Self-Editing, James Scott Bell, 2008
I've been stockpiling books on writing for a while and now I'm working through them. Bell knows about writing. Not only does he have a couple of dozen books out, but he took over Lawrence Block's column in Writer's Digest and has done three books on writing for Writer's Digest. I've already read The Art of War for Writers and am currently working on Plot & Structure.
This book is a great tool. It has two sections, self-editing and revisions. Last month I used the last chapter - The Ultimate Revision Checklist - as I worked on draft three of my current project, Endless Vacation. Very helpful.
