Thread sewn books
(Paperback, books with a spine where the sections of the book are sewn together with thread)
The most common examples are school books, school journals, novels, travel guides, autobiographies and ledgers.
After the text sections are printed and folded, they are gathered and sewn together, using a strong thread on a sewing machine to make a book block. This book block is then glued with a strong adhesive to the inner spine of the cover. This method of binding is most common for publications which are required to last long periods of time and need to be exceptionally durable.
