There is no spine in book binding, and the spine is exposed and usually fixed with thread or glue, so it is also called bare back thread binding or bare back glue binding.

Horseback binding: It is a process of using pre made staples on thin booklets, folding the inner pages and cover together, and directly binding them at the spine fold, called "horseback binding".

Although this type of binding is economical and fast, it does not have a spine that can hold text, and the binding strength is poor. It is not suitable for binding thicker paper pages and is only suitable for binding thinner corporate brochures, magazines, or picture books.
