As early as the Jian Ce period, books already had certain binding methods. For example, the use of redundant slips (a few blank slips with no writing on the front of the volume) and standard slips (the rightmost slip with the title of the chapter on the back) is recognized as the origin of supplementary pages and covers in later books. After printed books became popular in the Song Dynasty, the binding form of books became increasingly perfect. For example, the structure of a thread-bound book includes book jacket, bookmark, cover, inside cover, leaf, lining leaf, book cover, book back, book root, book corner and other items.
"Book cover", commonly known as "book cover", is the paper on the surface of a book. In modern times, it is called "seal" or "envelope". It is generally made of harder and thick colored paper or colored silk, and is placed outside the cover of the book to protect and decorate the book. The book cover can be divided into single leaf and double leaf. The single leaf is called "koupi" and the double leaf is called "zongzipi".
"Bookmark", also known as "floating mark", or "book cover mark", is a paper mark affixed to the book jacket, sometimes made of silk fabric, used to inscribe the title, volume or volume of the book. number.
The "cover" is the first page after the book jacket, which is equivalent to the modern title page, also known as the "title page". It is often printed with the title of the book, author's name, publisher's name, publication date, etc. . Particular attention is paid to the calligraphy of the book title and the signature of the inscriber, which is often covered with tissue paper.
The "back cover", commonly known as "cover two", is the back side of the cover, which is mostly blank, but sometimes has text printed on it.
"Leaf" refers to the blank page between the book jacket and the cover. The one added at the front is called "front leaf", and the one added at the back is called "back leaf", also called "auxiliary leaf". Its function can protect the leaves of the main book and prevent moisture and insects, so it is also called "leaf protector". There can also be inscriptions and postscripts on the title page.
"Lining leaves" refers to the blank pages lining the front and back of the book.
"Book brain" refers to the blank space outside the left and right sidebars of the thread-bound book leaves for drilling and stitching. Because it is the key position during binding and the hub for fixing the form of the book, it is called "book brain".
"Book back", also known as "book spine", refers to the side where the book leaves are bound and sewn together, just like the back of a book.
"Book root" refers to the side cutout at the bottom of each book. Thread-bound books can only be placed flat on bookshelves, so bibliophiles write the title, volume or volume number on the book base to facilitate inspection and sorting.
"Book header", also known as "book header", refers to the side cutout at the top of each book.
"Book corner" refers to the upper and lower corners on the right side of a book. For more precious books, when binding, the corners of the book are often wrapped with lake-colored or blue silk, which is called "corner wrapping."
"Han", also known as "Letter Set", is used to hold books. The types of letter covers include book covers, paper boxes, wooden boxes, plywood, etc. The "book cover" is made of cardboard, with paper on the inside and cloth on the outside. If the upper and lower sides are tightly sealed, it is called a "four-in-one cover". Those made into a crescent shape at the opening of the letter are called "crescent sleeves"; those made into a cloud or ring shape at the opening of the letter are called "cloud head sleeves". The "paper box" is made of paper and consists of an inner three-sided book box and an outer five-sided box cover. It is opened from the longitudinal side of the book box, and the title, author, book number, volume, and volume of the book are written on the other fixed longitudinal side. Books, functions, etc. The "wooden box" is made of nanmu and other hardwoods and is made into a five-sided closed box cover. When holding books, two wooden blocks are used to cushion the top and bottom of the book. "Plywood" is simplified from a wooden box. A paper tape is passed through the flat holes on the upper and lower plywood. The cover is the name given to the book blocks that are bound into a volume and pasted with a coat on the outside. The cover is also called a book cover. , cover, outer cover, etc., and are divided into cover one, cover two (belonging to the front cover), cover three, and cover four (belonging to the back cover).
