A book is both a usually portable physical object and the body of immaterial representations or intellectual object whose material signs—written or drawn lines or other two-dimensional media—the physical object contains or houses.

As a physical object, a book is a stack of usually rectangular pages (made of papyrus, parchment, vellum, or paper) oriented with one side (either left or right, depending on the direction in which one reads a script) tied, sewn, or otherwise fixed together and then bound to the flexible spine of a protective cover of heavier, relatively inflexible material so that, when the opened front cover has received a massy enough stack of sheets, the book can lie flat. The technical term for this physical arrangement is codex (in the plural, codices). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its immediate predecessor, the scroll.

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 a still considerable, though not so extensive, investment of time to read. This sense of book has a restricted and an unrestricted sense. In the restricted sense, a book is a self-sufficient section or part of a longer composition, a usage that reflects the fact that, in antiquity, long works had to be written on several scrolls, and each scroll had to be identified by the book it contained. So, for instance, each part of Aristotle's Physics is called a book, as of course the Bible encompasses many different books. In the unrestricted sense, a book is the compositional whole of which such sections, whether called books or chapters or parts, are parts.

But the intellectual content in a physical book need not be a composition, or can be called a book. Books can consist only of drawings, engravings, or photographs, or such things as crossword puzzles or cut-out dolls. In a physical book the pages can be left blank or can feature an abstract set of lines as support for on-going entries, i.e., an account book, an appointment book, a log book, an autograph book, a notebook, a diary or day book, or a sketch book. 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 e-books and other formats. In its "Revised Recommendation concerning the International Standardization of Statistics on the Production and Distribution of Books, Newspapers and Periodicals" of 1 November 1985, the United Nations Educational, Scientific and Cultural Organization (UNESCO) stated that it was "convinced that it is desirable that the national authorities responsible for collecting and reporting statistics relating to the production and distribution of printed publications should be guided by certain standards in the matter of definitions, classification and presentation," and so "in order to improve the international comparability of statistics," it defined a book as "a non-periodic publication of at least 49 pages exclusive of the cover pages, published in the country and made available to the public" (11(a)), so that books statistics could be collected on "(a) Government publications, i.e., publications issued by public administrations or their subsidiary bodies, except for those which are confidential or designed for internal distribution only; (b) School textbooks, books prescribed for pupils receiving education at the first and second level as defined in the revised Recommendation concerning the International Standardization of Educational Statistics adopted by the General Conference; (c) University theses; (d) Offprints, i.e., reprints of a part of a book or a periodical already published, provided that they have a title and a separate pagination and that they constitute a distinct work; (e) Publications which form part of a series, but which constitute separate bibliographical units; (f) Illustrated works: (i) Collections of prints, reproductions of works of art, drawings, etc., when such collections form complete, paginated volumes and when the illustrations are accompanied by an explanatory text, however short, referring to these works or to the artists themselves; (ii) Albums, illustrated books and pamphlets written in the form of continuous narratives, with pictures illustrating certain episodes; (iii) Albums and picture-books for children; (iv) Comic books" (9-10). A single sheet in a codex is a leaf, and each side of a leaf is a page.

Although in ordinary academic parlance a monograph is understood to be a specialist academic work, rather than a reference work on a single 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 or a book lover is a bibliophile or colloquially, "bookworm". A shop where books are bought and sold is a bookshop or bookstore. Books are also sold elsewhere. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 distinct titles had been published. In some wealthier nations, the sale of printed books has decreased because of the use of e-books, though sales of e-books declined in the first half of 2015.

James Madison, author of Federalist No. 10

Federalist No. 10 (Federalist Number 10) is an essay by James Madison and the tenth of the Federalist Papers, a series arguing for the ratification of the United States Constitution. It was published on November 22, 1787, under the pseudonym Publius, the name under which all the Federalist Papers were published. The essay is the most famous of the Federalist Papers, along with Federalist No. 51, also by James Madison, and is among the most highly regarded of all American political writings.No. 10 addresses the question of how to guard against "factions," groups of citizens with interests contrary to the rights of others or the interests of the whole community. In today's discourse the term special interest often carries the same connotation. Madison argued that a strong, large republic would be a better guard against those dangers than smaller republics—for instance, the individual states. It is believed that James Madison took ideas from Thomas Hobbes in regards to ideas of a strong controlling government. Opponents of the Constitution offered counterarguments to his position, which were substantially derived from the commentary of Montesquieu on this subject.

After a 244-year span in print, the Encyclopædia Britannica will discontinue its published volumes. With less than 1% of revenue coming from print versions, Jorge Cauz, Britannica's president, indicates there simply is not sufficient demand for the print publication. In the last 11 years demand has plummeted due to competition from Wikipedia and Britannica's own digital version. Britannica peaked in sales in 1990 with 120,000 sets sold. The 2010 edition will be the last in print and has sold 8,000 sets to date; with 4,000 sets remaining.

Selected biography

Thomas Ruggles Pynchon, Jr. (born May 8, 1937) is an American writer based in New York City, noted for his dense and complex works of fiction. Hailing from Long Island, Pynchon spent two years in the United States Navy and earned an English degree from Cornell University. After publishing several short stories in the late 1950s and early 1960s, he began composing the novels for which he is best known today: V. (1963), The Crying of Lot 49 (1966), Gravity's Rainbow (1973), Vineland (1990), Mason & Dixon (1997), and Against the Day (2006).Pynchon (/ˈpɪnɒn/, with /ˈpɪntʃən/ a common mispronunciation) is regarded by many readers and critics as one of the finest contemporary authors. He is a MacArthur Fellow and a recipient of the National Book Award, and is regularly cited as a contender for the Nobel Prize in Literature. Both his fiction and non-fiction writings encompass a vast array of subject matter, styles and themes, including (but not limited to) the fields of history, science and mathematics. Pynchon is also known for his avoidance of personal publicity: very few photographs of him have ever been published, and rumours about his location and identity have been circulated since the 1960s.
