Two major commercial bookbinding techniques are used today: traditional and perfect binding (or adhesive binding).

Many variations exist for each of these techniques as well. 

Traditional binding is generally used on hardcover, or hardbound, books. However, perfect binding (developed originally for paperback books) is being used widely as more durable adhesives are being developed. 

In reality, perfect binding is one of many forms of adhesive binding.  

Our Transparent White Spine Glue is one of Bookbinding Glue for a perfect binding machine.
