I guess I'm with you Scion. I constantly write in my books. I don't really bother with erratas but I write up characters in my books and scribble little notes in them during play. The way I see it, I could care less if it's a book. It's paper. It's meant to be written on. As long as I can stil see the original writing I don't mind if it's doodled on. Hell, I don't care that the cover of my phb is almost falling off, as long as I have all the individual papers in the right order it's fine by me.
