Personally, I prefer trade paperback followed by mass market paperbacks and in last place hardcover books. I prefer paper books to ebooks although I'm sure that will change once I stop dillydallying and just buy an ereader. I'm not loyal to genres but am loyal to authors. If I find an author I like, I try to read all their work. I like checking the new book section of the library; it's a great place to find authors and books you would have never found otherwise.I found Swallow by Sefi Atta this way. What are your book habits.
