    Hardcover books have appeared in the Qing Dynasty, which is the western imported method. Later, many books in the West, such as the Bible and Code, were mostly in hardcover. The "New Testament" which published by Meihua Bookstore in the 20th year of Guangxu of Qing Dynasty is a hardcover book. The cover is inlaid with gold lettering and is very gorgeous. The biggest advantage of hardcover books is that the cover is sturdy and protects the inner pages, making the book durable. The inner pages of hardcover books are the same as paperbacks. They are mostly thread-locking staples, and a cloth strip is attached to the spine for more secure connection and protection. The cover material is thick and hard. The front and back cover are adhered to the beginning and end of the book, respectively. The spine of the cover and inside spine are mostly non-adhesive, so that the inner pages are not always affected when flipping. The spine is divided into flat ridges and round ridges. Flat ridges are mostly lined with cardboard for protection and have a flat shape. Round ridges are mostly lined with kraft paper, leather and other tough materials to facilitate arcing. The cover and spine should be creased and ridged to open the cover. Hardcover books are exquisitely printed, not easy to break, easy to use and save for a long time, special design requirements, and the selection of materials and process technology are more complicated, so there are many places worth studying.
