As for me, I usually prefer softback books, as they are easier for me to hold and read. I might get a hardback if the book doesn’t come in softback form or if the book is perhaps a very special one to me.
I do hear you there. If it's one I want to keep and really like, not just read once, I prefer hardback. Otherwise I pass along most books I've read anyways.
Depends on the book. If it's a one read and lost on the shelf, softback. If it is a Spiritual Masters writings definitely Hardback to preserve if available. If Something that i might be referencing quite a bit...hardcover is cool but soft back is good as well.
Hardback. I love my books and keep them forever. I write in them, make notes sometimes, turn down the corners, etc. That's why I don't get books from the library very often. And I'll never read from an electronic device. I do sometimes, especially if it a book that is required reading for whatever reason. I never stopped using the library for videos, CDs, and audio books.
