About books
A book is a set or collection of written, printed, illustrated, or blank sheets, made of ink, paper,parchment, or other materials, usually fastened together to hinge at one side. A single sheet within a book is called a leaf or leaflet, and each side of a leaf is called a page. A book produced in electronic format is known as an electronic book (e-book).
Books may also refer to works of literature, or a main division of such a work. In library and information science, a book is called a monograph, to distinguish it from serial periodicals such as magazines,journals or newspapers. The body of all written works including books is literature. In novels and sometimes other types of books (for example, biographies), a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, and so on). A lover of books is usually referred to as a bibliophile, a philologist, or, more informally, a bookworm.
A store where books are bought and sold is a bookstore or bookshop. Books can also be borrowed from libraries. In 2010, Google estimated that since the invention of printing, approximately 130,000,000 unique titles had been published.
Etymology
The word comes from Old English "bōc" which itself comes from the Germanic root "*bōk-", cognate to beech. Similarly, in Slavic languages (for example, Russian, Bulgarian) "буква" (bukva—"letter") is cognate with "beech". In Russian and in Serbian, another Slavic language, the words "букварь" (bukvar') and "буквар" (bukvar), respectively, refer specifically 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. Similarly, the Latin word codex, meaning a book in the modern sense (bound and with separate leaves), originally meant "block of wood".

Antiquity
When writing systems were invented in ancient civilizations, nearly everything that could be written upon—stone, clay, tree bark, metal sheets—was used for writing.The study of such inscriptions forms a major part of history.The study of inscriptions is known as epigraphy. Alphabetic writingemerged in Egypt about 5,000 years ago. The Ancient Egyptians would often write on papyrus, a plant grown along the Nile River. At first the words were not separated from each other (scriptural continua) and there was no punctuation. Texts were written from right to left, left to right, and even so that alternate lines read in opposite directions. The technical term for this type of writing is 'boustrophedon,' which means literally 'ox-turning' for the way a farmer drives an ox to plough his fields.
Scroll
Main article: Scroll
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, 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 Nefertiti Kakai of the Fifth Dynasty (about 2400 BC). Papyrus sheets were glued together to form a scroll. Tree bark such as lime (Latin liber, from which also comes library) 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, and Hebrew 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
