Wikipedia
From Wikipedia, the free encyclopedia
Wikipedia (pronounced /ˌwiːkiˈpiːdi.ə/, WEE-kee-PEE-dee-ə or /ˌwɪkɨˈpiːdi.ə/, WI-ki-PEE-dee-ə) is a free,[5] web-based, collaborative, multilingual encyclopedia project supported by the non-profit Wikimedia Foundation. Its name is a portmanteau of the words wiki (a technology for creating collaborative websites, from the Hawaiian wordwiki, meaning "quick") and encyclopedia. Wikipedia's 13 million articles (three million in the English Wikipedia) have been written collaboratively by volunteers around the world, and almost all of its articles can be edited by anyone with access to the site.[6]Launched in 2001 by Jimmy Wales and Larry Sanger,[7] it is currently the largest and most popular general reference work on the Internet.[3][8][9][10]
Critics of Wikipedia accuse it of systemic bias and inconsistencies (including undue weight given to popular culture),[11] and allege that it favors consensus over credentials in its editorial process.[12] Its reliability and accuracy are also claimed to be an issue.[13] Other criticisms center on its susceptibility to vandalism and the addition of spurious or unverified information,[14] though scholarly work suggests that vandalism is generally short-lived,[15][16] and an investigation in Nature found that the material they compared came close to the level of accuracy of Encyclopædia Britannica and had a similar rate of "serious errors".[17] These claims have been disputed by Encyclopædia Britannica;[18] Nature in turn published a rebuttal to Britannica's objections.[19]
Wikipedia's departure from the expert-driven style of the encyclopedia building mode and the large presence of unacademic contents have been noted several times. WhenTime magazine recognized You as its Person of the Year for 2006, acknowledging the accelerating success of online collaboration and interaction by millions of users around the world, it cited Wikipedia as one of several examples of Web 2.0 services, along with YouTube, MySpace, and Facebook.[20] Some noted the importance of Wikipedia not only as an encyclopedic reference but also as a frequently updated news resource because of how quickly articles about recent events appear.[21][22]

A book is a set or collection of written, printed, illustrated, or blank sheets, made of paper, parchment, or other material, usually fastened together to hinge at one side. A single sheet within a book is called a leaf, and each side of a leaf is called a page. A book produced in electronic format is known as an e-book.
Books may also refer to a literature work, 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, journalsor newspapers. The body of all written works including books is literature.
In novels, a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, etc).
A lover of books is usually referred to as a bibliophile, a bibliophilist, or a philobiblist, or, more informally, abookworm.
A store where books are bought and sold is a bookstore or bookshop. Books can also be borrowed fromlibraries.
