The document provides information on various book binding methods including saddle-stitch, case, perfect, tape, and Japanese binding. Saddle-stitch binding is an inexpensive method where signatures are wire-stitched through the center fold and then trimmed. Case binding uses signatures gathered and sewn into a book block which is attached to rigid covers. Perfect binding glues signatures to cardboard covers for a clean edge but the book cannot lie flat. Tape binding is similar but uses tape wrapped around the glued spine. Japanese binding punches or drills holes along the spine edge and stitches the signatures with thread.
