I like that. My LY and RW are pretty raggedy, and I've basically written my own indexes for those books. (Let's not forget the other books: Hutton, Thompson, Road to Logic, Bird's Pearls (which i haven't read))
I remember staying in a friend's basement flat in South London, and taking baths with HSoE. The book was largely destroyed by the time I got on the plane home, but I was entranced.
