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.
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). An avid reader of books is a bibliophile or colloquially, bookworm.
A shop where books are bought and sold is a bookshop or bookstore. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 unique titles had been published. In some wealthier nations, printed books are giving way to the usage of electronic or e-books, though sales of e-books declined in the first half of 2015.
Keturi brūkšniai is a polemical book by Lithuanian historian Edvardas Gudavičius, written in the Lithuanian language. It was published in 2002 by Aidai in Vilnius (ISBN 9955-445-55-6). It does not have any proper title, but publishers and book sellers usually put four dashes (Lithuanian: Keturi brūkšniai) as the title.
In graph theory, a book graph (often written ) may be any of several kinds of graph.
One kind, which may be called a quadrilateral book, consists of p quadrilaterals sharing a common edge (known as the "spine" or "base" of the book). A book of this type is the Cartesian product of a star and K2 .
A second type, which might be called a triangular book, is the complete tripartite graph K1,1,p. It is a graph consisting of triangles sharing a common edge. A book of this type is a split graph.
This graph has also been called a
.
Given a graph , one may write
for the largest book (of the kind being considered) contained within
.
The term "book-graph" has been employed for other uses. Barioli used it to mean a graph composed of a number of arbitrary subgraphs having two vertices in common. (Barioli did not write for his book-graph.)

Might blow a bag of hershey in the sidd-ix
Or might take sips of army with a chidd-ick, I'm so sick widdit
Lampin in the Hamptons, the weekends man

Or playin guts on the cruise, Hermes bow shoes
The Izod bucket on I'm so old school
Yellow wrist watch, Gucci flip flops
Six top model chicks, who is this hot?

We in Luan (whoo!) gettin our groove on
Buyin out the bar, on our way to Spa'
She never seen a hundred on the wrist before
Never seen twenty-two's on the 6 before

Cause the boy got more 6's than first grade
The crib got, killer views and square feet
You have to film MTV Cribs for a week
So, sleep if you need to, mami I will leave you
Right where you stand, nah I don't wanna dance (I'm good)
I just wanna see what's in your Frankie V pants
Waist is low enough to let your waist show
Top like a rock star, I got a fast car
We can cruise the city, doin a buck-sixty
[Chorus]
[Jay-Z]
"He did it again!" Haters no like
But they gotta fuck with it cause the flow's so tight
Gnarly dude! I puff Bob Marley dude
All day, like Rastafari's do
Now I'm stuck to the point I could hardly move
You fuckin up my high, don't bother me dude
But Red Rover, send your hoes over
She can do WHATEVER, sip somethin with soda
She can leave WHENEVER, sip somethin with Hova
We can play HOWEVER, slay bed or sofa
And the prognosis, sex is explosive
Left her with wet bedsheets, nigga I'm focused
[Chorus]
