Swiss binding
A rarity in the world of bookbinding: the book block is here glued to the back case board only, and when you open the book you will see the folds. The spine of the (thread-sewn) block is often shrouded with crepe, but sometimes the publishers decide to leave it bare.
Swiss-bound books are characterised by very good openability, so this type of binding is recommended to use in unusual publications, such as portfolios, art exhibition catalogues or other collector’s printed matter.
