Hardcover? Or paperback?
Paperbacks for almost everything. The only types of books I prefer hardcovers for are art/design books that have to stand the test of time and me touching me all the time. I pull them out and look at them a lot more than novels so they need to deal with more wear. Besides that, paperbacks all the way. They are so much easier to hold and don't poke you in the hands!
Illustrations? Or just text?
Both! Sometimes individually, sometimes together! I love graphic novels and design books so sometimes you just don't need words!
First editions? Or you don’t care?
Don't really care. Though, I do have an ARC of a book that was pulled from the shelf for plagiarism so that's kind of interesting. Doesn't really have anything to do with the question but yeah...
Signed by the author? Or not?
Signed books are always nice but I still love my un-signed books :)
So, what about you! This was a fun one!
