Book binding is one of the world's oldest art forms. Over the centuries, its many variations have been traded across cultures, growing and changing with new technologies. Many of those unique variations still persist today. So many, in fact, that it can be difficult to decide which book binding method is best for your book.
Most softcover and hardcover books are bound using an adhesive glue. Spiral bound books, on the other hand, have series of small holes punched into the left-hand side of their pages. A coil is fed through these holes to form the binding. Most spiral coils are made from plastic, but some are bound with a metal coil called Wire-O. Wire-O offers the same level of flexibility with an added touch of sophistication.
