Unlike printed encyclopedias, Wikipedia is continually created and updated, with articles on historic events appearing within minutes, rather than months or years.

Wikipedia's homepage for all languages</div> </div> </div> <p><a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia" title="Wikipedia">Wikipedia</a> was founded as an offshoot of <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Nupedia" title="Nupedia">Nupedia</a>, a now-abandoned project to produce a free encyclopedia. Nupedia had an elaborate system of <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Peer_review" title="Peer review">peer review</a> and required highly qualified contributors, but the writing of articles was slow. During 2000, <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Jimmy_Wales" title="Jimmy Wales">Jimmy Wales</a>, founder of Nupedia, and <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Larry_Sanger" title="Larry Sanger">Larry Sanger</a>, whom Wales had employed to work on the project, discussed ways of supplementing Nupedia with a more open, complementary project. Multiple sources suggested that a <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wiki" title="Wiki">wiki</a> might allow members of the public to contribute material, and Nupedia's first wiki went online on January 10, 2001.</p> <p>There was considerable resistance on the part of Nupedia's editors and reviewers to the idea of associating Nupedia with a website in the wiki format, so the new project was given the name "Wikipedia" and launched on its own domain, wikipedia.com, on January 15 (now called <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Day" title="Wikipedia:Wikipedia Day">"Wikipedia Day"</a> by some users).

Over time, this generally results in an upward trend of quality and a growing consensus over a neutral representation of information.<sup class="Template-Fact" style="white-space:nowrap;">[<i><a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources">citation needed</span></a></i>]</sup></p> <p>Users should be aware that not all articles are of encyclopedic quality from the start: they may contain false or debatable information. Indeed, many articles start their lives as displaying a single viewpoint; and, after a long process of discussion, debate, and argument, they gradually take on a <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:NPOV" title="Wikipedia:NPOV" class="mw-redirect">neutral point of view</a> reached through <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Consensus" title="Wikipedia:Consensus">consensus</a>. Others may, for a while, become caught up in a heavily unbalanced viewpoint which can take some time—months perhaps—to achieve better balanced coverage of their subject. In part, this is because editors often contribute content in which they have a particular interest and do not attempt to make each article that they edit comprehensive. However, eventually, additional editors expand and contribute to articles and strive to achieve balance and comprehensive coverage. In addition, Wikipedia operates a number of internal resolution processes that can assist when editors disagree on content and approach. Usually, editors eventually reach a consensus on ways to improve the article.</p> <p>The <i>ideal</i> Wikipedia article is well-written, balanced, <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Neutral_point_of_view" title="Wikipedia:Neutral point of view">neutral</a>, and encyclopedic, containing comprehensive, notable, <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Verifiability" title="Wikipedia:Verifiability">verifiable</a> knowledge. An increasing number of articles reach this standard over time, and many already have. Our best articles are called <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Featured_articles" title="Wikipedia:Featured articles">Featured Articles</a> (and display a small star in the upper right corner of the article), and our second best tier of articles are designated <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Good_Articles" title="Wikipedia:Good Articles" class="mw-redirect">Good Articles</a>. However, this is a process and can take months or years to be achieved, as each user adds their contribution in turn. Some articles contain statements which have not yet been fully <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:CITE" title="Wikipedia:CITE" class="mw-redirect">cited</a>. Others will later be augmented with new sections. Some information will be considered by later contributors to be insufficiently founded and, therefore, may be removed.</p> <p>While the overall trend is toward improvement, it is important to use Wikipedia carefully if it is intended to be used as a research source, since individual articles will, by their nature, vary in quality and maturity. <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Researching_with_Wikipedia" title="Wikipedia:Researching with Wikipedia">Guidelines and information pages</a> are available to help users and researchers do this effectively, as is an article that summarizes third-party studies and assessments of the <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Reliability_of_Wikipedia" title="Reliability of Wikipedia">reliability of Wikipedia</a>.</p> <h3> <span class="mw-headline" id="Wikipedia_vs_paper_encyclopedias">Wikipedia <abbr class="abbr" title="versus">vs</abbr> paper encyclopedias</span></h3> <ul> <li><i>Main article: <a href="//web.archive.org/web/20130130192436/http://meta.wikimedia.org/wiki/Wiki_is_not_paper" class="extiw" title="m:Wiki is not paper">Wiki is not paper</a>, on <a href="//web.archive.org/web/20130130192436/http://meta.wikimedia.org/wiki/" class="extiw" title="m:">Wikimedia Meta-Wiki</a></i>.</li> </ul> <p>Wikipedia has advantages over traditional paper encyclopedias. Wikipedia has a very low "publishing" cost for adding or expanding entries and a low environmental impact <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Environmental_impact_of_paper" title="Environmental impact of paper">in some respects</a>, since it never needs to be printed, although computers have their own <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Computers_and_the_environment" title="Computers and the environment" class="mw-redirect">environmental cost</a>. In addition, Wikipedia has <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikilink" title="Wikilink" class="mw-redirect">wikilinks</a> instead of in-line explanations and it incorporates overview summaries (article introductions) with the extensive detail of full articles. Additionally, the editorial cycle is short. A paper encyclopedia stays the same until the next edition, whereas editors can update Wikipedia at any instant, around the clock, to help ensure that articles stay abreast of the most recent events and scholarship.</p> <h3> <span class="mw-headline" id="Strengths.2C_weaknesses.2C_and_article_quality_in_Wikipedia">Strengths, weaknesses, and article quality in Wikipedia</span></h3> <div class="rellink relarticle mainarticle">Main pages: <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Why_Wikipedia_is_so_great" title="Wikipedia:Why Wikipedia is so great">Wikipedia:Why Wikipedia is so great</a> and <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Why_Wikipedia_is_not_so_great" title="Wikipedia:Why Wikipedia is not so great">Wikipedia:Why Wikipedia is not so great</a></div> <div class="rellink boilerplate seealso">See also: <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Reliability_of_Wikipedia" title="Reliability of Wikipedia">Reliability of Wikipedia</a> and <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Researching_with_Wikipedia" title="Wikipedia:Researching with Wikipedia">Wikipedia:Researching with Wikipedia</a></div> <p>Wikipedia's greatest strengths, weaknesses, and differences all arise because it is open to anyone, it has a large contributor base, and its articles are written by consensus, according to editorial guidelines and policies.</p> <ul> <li>Wikipedia is <b>open to a large contributor base</b>, drawing a large number of editors from diverse backgrounds. This allows Wikipedia to significantly reduce regional and cultural bias found in many other publications, and makes it very difficult for any group to censor and impose bias. A large, diverse editor base also provides access and breadth on subject matter that is otherwise inaccessible or little documented. A large number of editors contributing at any moment also means that Wikipedia can produce encyclopedic articles and resources covering newsworthy events within hours or days of their occurrence. It also means that like any publication, Wikipedia may reflect the cultural, age, socio-economic, and other biases of its contributors. There is no systematic process to make sure that <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:List_of_articles_all_languages_should_have" title="Wikipedia:List of articles all languages should have" class="mw-redirect">"obviously important" topics</a> are written about, so Wikipedia may contain unexpected oversights and omissions. While <i>most</i> articles may be altered by anyone, in practice editing will be performed by a certain demographic (younger rather than older, male rather than female, rich enough to afford a computer rather than poor, et cetera) and may, therefore, show some bias. Some topics may not be covered well, while others may be covered in great depth.</li> </ul> <ul> <li>Allowing <b>anyone to edit</b> Wikipedia means that it is more easily vandalized or susceptible to unchecked information, which requires removal. See <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Administrator_intervention_against_vandalism" title="Wikipedia:Administrator intervention against vandalism">Wikipedia:Administrator intervention against vandalism</a>. While blatant vandalism is usually easily spotted and rapidly corrected, Wikipedia is more subject to subtle viewpoint promotion than a typical reference work. However, bias that would be unchallenged in a traditional reference work is likely to be ultimately challenged or considered on Wikipedia. While Wikipedia articles generally attain a good standard after editing, it is important to note that fledgling articles and those monitored less well may be susceptible to vandalism and insertion of false information. Wikipedia's radical openness also means that any given article may be, at any given moment, in a bad state, such as in the middle of a large edit, or a controversial rewrite. Many contributors do not yet comply fully with key <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Policies_and_guidelines" title="Wikipedia:Policies and guidelines">policies</a>, or may add information without <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:CITE" title="Wikipedia:CITE" class="mw-redirect">citable</a> sources. Wikipedia's open approach tremendously increases the chances that any particular factual error or misleading statement will be relatively promptly corrected. Numerous editors at any given time are monitoring <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Special:RecentChanges" title="Special:RecentChanges">recent changes</a> and edits to articles on their <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Watchlist" title="Wikipedia:Watchlist" class="mw-redirect">watchlist</a>.</li> </ul> <ul> <li>Wikipedia is <b>written by open and transparent consensus</b>—an approach that has its pros and cons. Censorship or imposing "official" points of view is extremely difficult to achieve and usually fails after a time. Eventually for most articles, all notable views become fairly described and a <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:NPOV" title="Wikipedia:NPOV" class="mw-redirect">neutral point of view</a> reached. In reality, the process of reaching consensus may be long and drawn-out, with articles fluid or changeable for a long time while they find their "neutral approach" that all sides can agree on. Reaching neutrality is occasionally made harder by <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Tendentious_editing" title="Wikipedia:Tendentious editing">extreme-viewpoint contributors</a>. Wikipedia operates a full editorial dispute resolution process, one that allows time for discussion and resolution in depth, but one that also permits disagreements to last for months before poor-quality or biased edits are removed. A common conclusion is that Wikipedia is a valuable resource and provides a good reference point on its subjects.</li> </ul> <ul> <li>That said, articles and subject areas sometimes suffer from significant omissions, and while misinformation and vandalism are usually corrected quickly, this does not always happen. (See for example <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia_biography_controversy" title="Wikipedia biography controversy">this incident</a> in which a person inserted a fake biography linking a prominent journalist to the Kennedy assassinations and Soviet Russia as a joke on a co-worker which went undetected for four months, saying afterwards he "didn’t know <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia" title="Wikipedia">Wikipedia</a> was used as a serious reference tool".)</li> </ul> <ul> <li>Wikipedia is <b>written largely by amateurs</b>. Those with expert credentials are given no additional weight.

Wikipedia is also not subject to any peer review for scientific, medical or engineering articles. One advantage to having amateurs write in Wikipedia is that they have more free time on their hands so that they can make rapid changes in response to current events. The wider the general public interest in a topic, the more likely it is to attract contributions from non-specialists.</li> </ul> <p>The <a href="/web/20130130192436/http://en.wikipedia.org/wiki/MediaWiki" title="MediaWiki">MediaWiki</a> software that runs Wikipedia retains a history of all edits and changes, thus information added to Wikipedia never "vanishes". Discussion pages are an important resource on contentious topics. Therefore, serious researchers can often find a wide range of vigorously or thoughtfully advocated viewpoints not present in the consensus article. As with any source, information should be checked.

However, the consensus in Wikipedia is to put all disclaimers only as links and at the end of each article. Proposals to have a warning box at the beginning have been rejected.

That makes the updating of the encyclopedia very quick, almost as fast as news websites.</p> <h3> <span class="mw-headline" id="Editing_Wikipedia_pages">Editing Wikipedia pages</span></h3> <div class="rellink relarticle mainarticle">Main pages: <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:How_to_edit_a_page" title="Wikipedia:How to edit a page" class="mw-redirect">Wikipedia:How to edit a page</a> and <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Help:Wiki_markup" title="Help:Wiki markup">Help:Wiki markup</a></div> <p>Wikipedia uses a simple yet powerful page <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Markup_language" title="Markup language">layout</a> to allow editors to concentrate on adding material rather than page design. These include automatic sections and subsections, automatic references and cross-references, image and table inclusion, indented and listed text, links, ISBNs, and maths, as well as usual formatting elements and most world alphabets and common symbols. Most of these have simple formats that are deliberately very easy and intuitive.</p> <p>The page layout consists of tabs along the beginning. These are:</p> <ul> <li><i>Article.</i> Shows the main Wikipedia article.</li> <li><i>Discussion.</i> Shows a user discussion about the article's topic and possible revisions, controversies, etc.</li> <li><i>Edit.</i> This tab allows users to edit the article. Depending on the page’s susceptibility to vandalism, according to its visibility or the degree of controversy surrounding the topic, this tab may not be shown for all users. (For example, any user who is not an <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Administrators" title="Wikipedia:Administrators">administrator</a> will not be able to edit the <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Main_Page" title="Main Page">Main Page</a>).</li> <li><i>View history.</i> This tab allows readers to view the editors of the article and the changes that have been made.</li> <li><i>Star.</i> ("Watch") If you are logged in to your account, clicking on the star icon will cause any changes made to the article to be displayed on the watchlist.

This means that poor-quality edits or vandalism can quickly and easily be reversed or brought up to an appropriate standard by any other editor, so inexperienced editors cannot accidentally do permanent harm if they make a mistake in their editing.

Individuals often will choose to become involved in specialised tasks, such as reviewing articles at others' request, watching current edits for vandalism, watching newly created articles for quality control purposes, or similar roles. Editors who believe they can serve the community better by taking on additional administrative responsibility may ask their peers for agreement to undertake such responsibilities. This structure enforces meritocracy and communal standards of editorship and conduct. At present a minimum approval of 75–80% from the community is required to take on these additional tools and responsibilities. This standard tends to ensure a high level of experience, trust, and familiarity across a broad front of aspects within Wikipedia.</p> <p>A variety of <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Category:Wikipedia_counter-vandalism_tools" title="Category:Wikipedia counter-vandalism tools">software-assisted systems</a> and <a href="/web/20130130192436/http://en.wikipedia.org/wiki/Wikipedia:Bots" title="Wikipedia:Bots">automated programs</a> help editors and administrators to watch for problematic edits and editors. Theoretically all editors and users are treated equally with no "power structure". There is, however a hierarchy of permissions and positions, some of which are listed hereafter:</p> <ol> <li><i>Anyone</i> can edit most of the articles here. Some articles are protected due to vandalism or edit-warring, and can only be edited by certain editors.</li> <li>Anyone with an account that has been registered for four days or longer and has made at least ten edits becomes <i>autoconfirmed</i>, and gains the technical ability to do three things that non-autoconfirmed editors cannot: <ul> <li>Move articles.</li> <li>Edit semi-protected articles.</li> <li>Vote in certain elections (minimum edit count to receive suffrage varies depending on the election).</li> </ul> </li> <li>Many editors with accounts obtain access to certain tools that make editing easier and faster.
