Agree. Thats what counts for me to. Most of my collection is pockets in very good shape. Have perhaps 10 hardcovers. Were more once but since i started exchanging swedish hardcovers for english påockets some years back that have changed. But most admit I've read my copy of IT so many times i had to buy a new one of that one. But otherwise they are fine.I got a very nice hard copy of Eyes of the Dragon for seventy-five cents at Goodwill. I didn't have one so was quite pleased. also bought a hard copy version of The Shining for 10 dollars from a book seller in town as I didn't have that one either.
I have no idea if any of my books are worth anything at all. They are valuable to me and my collection, and that's what matters to me.
