Edition binding
The conventional method of bookbinding, producing "hardback" books. Signatures are
collated in sequence, endleaves pasted on the first and last signature, and then sewn
together. The book is then trimmed on three edges, the spine (or backbone) roughed up
and rounded (to lay flat when opened), and glue applied. At the same time, the covers
(or cases) are prepared separately. The book is then put into its case and pasted
together. After drying, a dust jacket may be added.
Perfect binding
Perfect binding is used to produce books without the expense of sewing and case-
binding. The process begins with placing signatures in sequence. The spine is then
lightly ground to rough up the edges for better adhesion. An adhesive is applied to the
spine, the cover attached and the publication is three-edge trimmed. Examples of
perfect bound books include paperbacks, manuals and thicker magazines.
