I used to buy paperbacks almost exclusively because of price and bulk. I only bought hardcovers of books I couldn't wait for the paperback (Terry Pratchett, I'm looking at you

) or of books I liked for their looks as well as the content.
Now I buy no more paperbacks and
more hardcovers than ever before. I buy all new books of several authors in hardcover (even signed limited editions)
and eBook and all of the books I used to buy in paperback only in ebooks.
