A book is a medium for recording information in the form of writing or images. Books are typically composed of many pages, bound together and protected by a cover. Modern bound books were preceded by many other written mediums, such as the codex and the scroll. The book publishing process is the series of steps involved in their creation and dissemination.
The codex was the historical ancestor of the modern book. Instead of being composed of sheets of paper, it used sheets of vellum, papyrus, or other materials. The term codex is often used for ancient manuscript books, with handwritten contents. A codex, much like the modern book, is bound by stacking the pages and securing one set of edges by a variety of methods over the centuries, yet in a form analogous to modern bookbinding. Modern books are divided into paperback and those bound with stiff boards, called hardbacks. Elaborate historical bindings are called treasure bindings. At least in the Western world, the main alternative to the paged codex format for a long document was the continuous scroll, which was the dominant form of document in the ancient world. Some codices are continuously folded like a concertina, in particular the Maya codices and Aztec codices, which are actually long sheets of paper or animal skin folded into pages. In Japan, concertina-style codices called orihon developed during the Heian period (794–1185) were made of paper.
Origami is the Japanese art of paper folding. In modern usage, the word "origami" is often used as an inclusive term for all folding practices, regardless of their culture of origin. The goal is to transform a flat square sheet of paper into a finished sculpture through folding and sculpting techniques. Modern origami practitioners generally discourage the use of cuts, glue, or markings on the paper. Origami folders often use the Japanese word kirigami to refer to designs which use cuts.
A handheld fan, or simply hand fan, is a broad, flat surface that is waved back-and-forth to create an airflow. Generally, purpose-made handheld fans are folding fans, which are shaped like a sector of a circle and made of a thin material mounted on slats which revolve around a pivot so that it can be closed when not in use. Hand fans were used before mechanical fans were invented.
Chinese culture is one of the world's oldest cultures, originating thousands of years ago. The culture prevails across a large geographical region in East Asia with Sinosphere in whole and is extremely diverse, with customs and traditions varying greatly between counties, provinces, cities, towns. The terms 'China' and the geographical landmass of 'China' have shifted across the centuries, before the name 'China' became commonplace in modernity.
The Yoshizawa–Randlett system is a diagramming system used to describe the folds of origami models. Many origami books begin with a description of basic origami techniques which are used to construct the models. There are also a number of standard bases which are commonly used as a first step in construction. Models are typically classified as requiring low, intermediate or high skill depending on the complexity of the techniques involved in the construction.
The discipline of origami or paper folding has received a considerable amount of mathematical study. Fields of interest include a given paper model's flat-foldability, and the use of paper folds to solve up-to cubic mathematical equations.
Modular origami or unit origami is a two-stage paper folding technique in which several, or sometimes many, sheets of paper are first folded into individual modules or units and then assembled into an integrated flat shape or three-dimensional structure, usually by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together.
The art of paper cutting in China may date back to the 2nd century CE, when paper was invented by Cai Lun, a court official of the Eastern Han dynasty.
Chinese paper folding, or zhezhi, is the art of paper folding that originated in medieval China.
Chinese calligraphy is the writing of Chinese characters as an art form, combining purely visual art and interpretation of the literary meaning. This type of expression has been widely practiced in China and has been generally held in high esteem across East Asia. Calligraphy is considered one of the four most-sought skills and hobbies of ancient Chinese literati, along with playing stringed musical instruments, the board game "Go", and painting. There are some general standardizations of the various styles of calligraphy in this tradition. Chinese calligraphy and ink and wash painting are closely related: they are accomplished using similar tools and techniques, and have a long history of shared artistry. Distinguishing features of Chinese painting and calligraphy include an emphasis on motion charged with dynamic life. According to Stanley-Baker, "Calligraphy is sheer life experienced through energy in motion that is registered as traces on silk or paper, with time and rhythm in shifting space its main ingredients." Calligraphy has also led to the development of many forms of art in China, including seal carving, ornate paperweights, and inkstones.
The history of books became an acknowledged academic discipline in the 1980s. Contributions to the field have come from textual scholarship, codicology, bibliography, philology, palaeography, art history, social history and cultural history. Its key purpose is to demonstrate that the book as an object, not just the text contained within it, is a conduit of interaction between readers and words. Analysis of each component part of the book reveals its purpose, where and how it was kept, who read it, ideological and religious beliefs of the period, and whether readers interacted with the text within. Even a lack of evidence of this nature leaves valuable clues about the nature of that particular book.
Paper craft is a collection of crafts using paper or card as the primary artistic medium for the creation of two or three-dimensional objects. Paper and card stock lend themselves to a wide range of techniques and can be folded, curved, bent, cut, glued, molded, stitched, or layered. Papermaking by hand is also a paper craft.
The size of a book is generally measured by the height against the width of a leaf, or sometimes the height and width of its cover. A series of terms is commonly used by libraries and publishers for the general sizes of modern books, ranging from folio, to quarto (smaller) and octavo. Historically, these terms referred to the format of the book, a technical term used by printers and bibliographers to indicate the size of a leaf in terms of the size of the original sheet. For example, a quarto historically was a book printed on sheets of paper folded in half twice, with the first fold at right angles to the second, to produce 4 leaves, each leaf one fourth the size of the original sheet printed – note that a leaf refers to the single piece of paper, whereas a page is one side of a leaf. Because the actual format of many modern books cannot be determined from examination of the books, bibliographers may not use these terms in scholarly descriptions.
Kirigami is a variation of origami, the Japanese art of folding paper. In kirigami, the paper is cut as well as being folded, resulting in a three-dimensional design that stands away from the page. Kirigami typically does not use glue.
Origami paper is used to fold origami, the art of paper folding. The only real requirement of the folding medium is that it must be able to hold a crease, but should ideally also be thinner than regular paper for convenience when multiple folds over the same small paper area are required.
Paper models, also called card models or papercraft, are models constructed mainly from sheets of heavy paper, paperboard, card stock, or foam.
Hotel toilet paper folding is a common practice performed by hotels worldwide as a way of assuring guests that the bathroom has been cleaned.
Bookbinding is the process of building a book, usually in codex format, from an ordered stack of paper sheets with one's hands and tools, or in modern publishing, by a series of automated processes. Firstly, one binds the sheets of papers along an edge with a thick needle and strong thread. One can also use loose-leaf rings, binding posts, twin-loop spine coils, plastic spiral coils, and plastic spine combs, but they last for a shorter time. Next, one encloses the bound stack of paper in a cover. Finally, one places an attractive cover onto the boards, and features the publisher's information and artistic decorations.
Paper toys are constructed in several ways, by folding, as in paper airplanes, paper fortune tellers or Origami, or by cutting, decorating or assembling pieces of paper with glue or tape to create a paper doll or paper model.
