You're making me want to sit down and do some rereading. although I have no idea when I'll have the time.

I too like having the addition background info on books. It's interesting that you're now satisfied with the edits you had to make. Because it is true they often do make the book better (in spite of the writer's intial feeling of otherwise). I remember when I read the original version of Stranger in a Strange Land thinking "Uh, no, Mr. Heinlein. The edited version is better. For one thing, Jill is less of an air-head in it."
