All other things (like price and storage space) being equal, given a choice in a perfect world, would you rather have paperbacks in your library? Or hardcovers? And why?
Hardcovers. They last longer, and they look better on a shelf or just lying around. I also like little extra things they sometimes do with hardcovers, like when they don’t trim the excess paper after the pages have been bound, so the edge has a rough, bumpy feel. It makes the book seem old and more sophisticated somehow.
I also don’t really mind reading them or carrying them around, but that’s not to say that I won’t buy a paperback if it’s a book I want to read.
