Perfect binding is a binding method that works by fastening the book block to the cover spine. A machine will lay hot glue on the binding edge of the complete book and then the cover is attached to it. It is often used for softcover books and is most familiar to people in the form of paperback books. It is also called adhesive binding, or unsewn binding.
Spiral binding is a punch-and-bind system that uses a plastic or metal spiral wire that is wound through punched holes on the binding edge. It is the type of binding most often used for school notebooks, cookbooks and steno pads.
Plastic Comb Binding
Also called GBC binding, plastic comb binding is a punch-and-bind system that is used for many office documents. Its main advantage is that it is inexpensive and easily edited. Its disadvantage is its appearance and the security of the final book.
Wire-O is a punch-and-bind system, similar to the plastic comb binding, but uses a wire to bind the pages together.
Wire stitching is a form of binding that uses wire staples to bind sheets together. Wire stitching can either be used as side stitching, or saddle stitching. Side stitching is used for thin books that are usually then either covered with a hard cover, or a tape strip. Saddle stitching binds the sheets together through the fold in the center of several pages. This form of binding is commonly used on comic books and magazines.
Sewn binding is usually used in conjunction with hard cover binding. The book block, or sections of the book block are sewn together prior to the addition of the cover. This makes for a very sturdy book. The biggest disadvantage to sewn binding is that it requires specialized, expensive equipment, and, when done on a custom basis, is a slow process.
Tape binding uses a thermoplastic adhesive on a strip to bind books. In technique, it is similar to perfect binding, where the individual pages are glued to the book spine. Tape binding is a good choice for office documents, review books, or other presentations.
Case bound books have a hard cover. These are usually covered with cloth, leather, dust jackets or textured paper. On some books, the spine has a different covering material than the front and back panels. This is called quarter-binding and is very popular in the publishing industry
