While acknowledging that we can’t judge books by their covers, how much does the design of a book affect your reading enjoyment? Hardcover vs. softcover? Trade paperback vs. mass market paperback? Font? Illustrations? Etc.? – BTT

I generally prefer hardcovers over softcovers. Having said that, they are heavy to carry around, and in the few times of the year when I buy books, I prefer trade paperbacks. I like their smooth covers, the better than mass market paper, their durability, and their pricing. They usually have better cover design than their mass market counterparts too. I also really love library editions or the hard binding that the libraries put on some paperbacks. As for font and illustrations, these things do not matter as much, but a nice cover is a nice cover.
