3. Book
A book is a set of written, printed, illustrated, or
blank sheets, made of ink, paper, parchment, or
other materials, fastened together to hinge at one
side. A single sheet within a book is a leaf, and each
side of a leaf is a page. A set of text-filled or
illustrated pages produced in electronic format is
known as an electronic book, or e-book.

4. Etymology
The word book comes from Old English "bōc" which
(itself) comes from the Germanic root "*bōk-", cognate
to beech.[2] Similarly, in Slavic languages (for example,
Russian, Bulgarian, Macedonian) "буква" (bukva—
"letter") is cognate with "beech". In Russian and in
Serbian and Macedonian, another Slavic languages, 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.[3] Similarly, the Latin word codex,
meaning a book in the modern sense (bound and with
separate leaves), originally meant "block of wood".

5. Antiquity
When writing systems were invented/created 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 writing emerged in Egypt . 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 (scriptura 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.
