iUniverse publishes soft cover books in perfect-bound format, a type of book binding that uses glue to hold the pages and cover together (typical of most professional books found in stores). We also publish hardcover books in two trim sizes: 5.5" x 8.5" or 6" x 9". We do not publish wire-o, plasticomb, three-ring, nor spiral-bound books.
