Book Book Medium for recording information in the form of writing or images Not to be confused with Textbook or Notebook. For other uses, see Book (disambiguation). A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is codex (plural, codices). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. The Gutenberg Bible, one of the first books to be printed using the printing press. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's Physics is called a book. In an unrestricted sense, a book is the compositional whole of which such sections, whether called books or chapters or parts, are parts. The intellectual content in a physical book need not be a composition, nor even be called a book. Books can consist only of drawings, engravings or photographs, crossword puzzles or cut-out dolls. In a physical book, the pages can be left blank or can feature an abstract set of lines to support entries, such as in an account book, an appointment book, an autograph book, a notebook, a diary or a sketchbook. Some physical books are made with pages thick and sturdy enough to support other physical objects, like a scrapbook or photograph album. Books may be distributed in electronic form as ebooks and other formats. Although in ordinary academic parlance a monograph is understood to be a specialist academic work, rather than a reference work on a scholarly subject, in library and information science monograph denotes more broadly any non-serial publication complete in one volume (book) or a finite number of volumes (even a novel like Proust's seven-volume In Search of Lost Time), in contrast to serial publications like a magazine, journal or newspaper. An avid reader or collector of books is a bibliophile or colloquially, "bookworm". A place where books are traded is a bookshop or bookstore. Books are also sold elsewhere and can be borrowed from libraries. Google has estimated that by 2010, approximately 130,000,000 titles had been published. In some wealthier nations, the sale of printed books has decreased because of the increased usage of ebooks. Etymology The word book comes from Old English bōc, which in turn comes from the Germanic root *bōk-, cognate to 'beech'. In Slavic languages like Russian, Bulgarian, Macedonian буква bukva—'letter' is cognate with 'beech'. In Russian, Serbian and Macedonian, the word букварь (bukvar') or буквар (bukvar) refers to a primary school textbook that helps young children master the techniques of reading and writing. It is thus conjectured that the earliest Indo-European writings may have been carved on beech wood. The Latin word codex, meaning a book in the modern sense (bound and with separate leaves), originally meant 'block of wood'. History Main article: History of books Antiquity Sumerian clay tablet, currently housed in the Oriental Institute at the University of Chicago, inscribed with the text of the poem Inanna and Ebih by the priestess Enheduanna, the first author whose name is known When writing systems were created in ancient civilizations, a variety of objects, such as stone, clay, tree bark, metal sheets, and bones, were used for writing; these are studied in epigraphy. Tablet Main articles: Clay tablet and Wax tablet See also: Stylus A tablet is a physically robust writing medium, suitable for casual transport and writing. Clay tablets were flattened and mostly dry pieces of clay that could be easily carried, and impressed with a stylus. They were used as a writing medium, especially for writing in cuneiform, throughout the Bronze Age and well into the Iron Age. Wax tablets were pieces of wood covered in a coating of wax thick enough to record the impressions of a stylus. They were the normal writing material in schools, in accounting, and for taking notes. They had the advantage of being reusable: the wax could be melted, and reformed into a blank. The custom of binding several wax tablets together (Roman pugillares) is a possible precursor of modern bound (codex) books. The etymology of the word codex (block of wood) also suggests that it may have developed from wooden wax tablets. Scroll Main article: Scroll Book of the Dead of Hunefer; c. 1275 BC; ink and pigments on papyrus; 45 × 90.5 cm; British Museum (London) Scrolls can be made from papyrus, a thick paper-like material made by weaving the stems of the papyrus plant, then pounding the woven sheet with a hammer-like tool until it is flattened. Papyrus was used for writing in Ancient Egypt, perhaps as early as the First Dynasty, although the first evidence is from the account books of King Neferirkare Kakai of the Fifth Dynasty (about 2400 BC). Papyrus sheets were glued together to form a scroll. Tree bark such as lime and other materials were also used. According to Herodotus (History 5:58), the Phoenicians brought writing and papyrus to Greece around the 10th or 9th century BC. The Greek word for papyrus as writing material (biblion) and book (biblos) come from the Phoenician port town Byblos, through which papyrus was exported to Greece. From Greek we also derive the word tome (Greek: τόμος), which originally meant a slice or piece and from there began to denote "a roll of papyrus". Tomus was used by the Latins with exactly the same meaning as volumen (see also below the explanation by Isidore of Seville). Whether made from papyrus, parchment, or paper, scrolls were the dominant form of book in the Hellenistic, Roman, Chinese, Hebrew, and Macedonian cultures. The more modern codex book format form took over the Roman world by late antiquity, but the scroll format persisted much longer in Asia. Codex Main article: Codex A Chinese bamboo book meets the modern definition of Codex Isidore of Seville (d. 636) explained the then-current relation between codex, book and scroll in his Etymologiae (VI.13): "A codex is composed of many books; a book is of one scroll. It is called codex by way of metaphor from the trunks (codex) of trees or vines, as if it were a wooden stock, because it contains in itself a multitude of books, as it were of branches." Modern usage differs. A codex (in modern usage) is the first information repository that modern people would recognize as a "book": leaves of uniform size bound in some manner along one edge, and typically held between two covers made of some more robust material. The first written mention of the codex as a form of book is from Martial, in his Apophoreta CLXXXIV at the end of the first century, where he praises its compactness. However, the codex never gained much popularity in the pagan Hellenistic world, and only within the Christian community did it gain widespread use. This change happened gradually during the 3rd and 4th centuries, and the reasons for adopting the codex form of the book are several: the format is more economical, as both sides of the writing material can be used; and it is portable, searchable, and easy to conceal. A book is much easier to read, to find a page that you want, and to flip through. A scroll is more awkward to use. The Christian authors may also have wanted to distinguish their writings from the pagan and Judaic texts written on scrolls. In addition, some metal books were made.
