Wikipedia is an online encyclopedia and, as a means to that end, an online community of individuals interested in building and using a high-quality encyclopedia in a spirit of mutual respect. Therefore, there are certain things that is not.
is not a paper encyclopedia, but a digital encyclopedia project. Other than verifiability and the other points presented on this page, there is no practical limit to the number of topics can cover or the total amount of content. However, there is an important distinction between what can be done, and what should be done, which is covered under § Encyclopedic content below. Consequently, this policy is not a free pass for inclusion: articles must abide by the appropriate content policies, particularly those covered in the five pillars.
Keeping articles to a reasonable size is important for's accessibility, especially for dial-up and mobile browser readers, since it directly affects page download time (see Wikipedia:Article size). Splitting long articles and leaving adequate summaries is a natural part of growth for a topic (see Wikipedia:Summary style). Some topics are covered by print encyclopedias only in short, static articles, but can include more information, provide more external links, and update more quickly.
Information should not be included in this encyclopedia solely because it is true or useful. A article should not be a complete exposition of all possible details, but a summary of accepted knowledge regarding its subject. Verifiable and sourced statements should be treated with appropriate weight. Although there are debates about the encyclopedic merits of several classes of entries, consensus is that the following are good examples of what is not. The examples under each section are not intended to be exhaustive.
is not a dictionary, or a usage or jargon guide. articles are not:
Definitions. Articles should begin with a good definition or description, but articles that contain nothing more than a definition should be expanded with additional encyclopedic content. If they cannot be expanded beyond a definition, is not the place for them. In some cases, the definition of a word may be an encyclopedic subject, such as the definition of planet. For a wiki that is a dictionary, visit our sister project Wiktionary. Dictionary definitions should be transwikied there.
Dictionary entries. Encyclopedia articles are about a person, or a group, a concept, a place, a thing, an event, etc. In some cases, a word or phrase itself may be an encyclopedic subject, such as Macedonia (terminology) or truthiness. However, articles rarely, if ever, contain more than one distinct definition or usage of the article's title. Articles about the cultural or mathematical significance of individual numbers are also acceptable.
is not a place to publish your own thoughts and analyses or to publish new information. Per our policy on original research, please do not use for any of the following:
Primary (original) research, such as proposing theories and solutions, original ideas, defining terms, coining new words, etc. If you have completed primary research on a topic, your results should be published in other venues, such as peer-reviewed journals, other printed forms, open research, or respected online publications. can report your work after it is published and becomes part of accepted knowledge; however, citations of reliable sources are needed to demonstrate that material is verifiable, and not merely the editor's opinion.
Personal essays that state your particular feelings about a topic (rather than the opinions of experts). Although is supposed to compile human knowledge, it is not a vehicle to make personal opinions become part of such knowledge. In the unusual situation where the opinions of an individual are important enough to discuss, it is preferable to let other people write about them. (Personal essays on-related topics are welcome in your user namespace or on the Meta-wiki.)
Discussion forums. Please try to stay on the task of creating an encyclopedia. You can chat with people about-related topics on their user talk pages, and should resolve problems with articles on the relevant talk pages, but please do not take discussion into articles. In addition, bear in mind that article talk pages exist solely to discuss how to improve articles; they are not for general discussion about the subject of the article, nor are they a help desk for obtaining instructions or technical assistance. Material unsuitable for talk pages may be subject to removal per the talk page guidelines. If you wish to ask a specific question on a topic, has a Reference desk; questions should be asked there rather than on talk pages.
is not a soapbox, a battleground, or a vehicle for propaganda, advertising and showcasing. This applies to usernames, articles, draftspace, categories, files, talk page discussions, templates, and user pages. Therefore, content hosted in is not for:
Advocacy, propaganda, or recruitment of any kind: commercial, political, scientific, religious, national, sports-related, or otherwise. An article can report objectively about such things, as long as an attempt is made to describe the topic from a neutral point of view. You might wish to start a blog or visit a forum if you want to convince people of the merits of your opinions.
Opinion pieces. Although some topics, particularly those concerning current affairs and politics, may stir passions and tempt people to "climb soapboxes", is not the medium for this. Articles must be balanced to put entries, especially for current events, in a reasonable perspective, and represent a neutral point of view. Furthermore, authors should strive to write articles that will not quickly become obsolete. However,'s sister project Wikinews allows commentaries on its articles.
Scandal mongering, promoting things "heard through the grapevine" or gossiping. Articles and content about living people are required to meet an especially high standard, as they may otherwise be libellous or infringe the subjects' right to privacy. Articles must not be written purely to attack the reputation of another person.
Self-promotion. It can be tempting to write about yourself or projects in which you have a strong personal involvement. However, remember that the standards for encyclopedic articles apply to such pages just like any other. This includes the requirement to maintain a neutral point of view, which can be difficult when writing about yourself or about projects close to you. Creating overly abundant links and references to autobiographical sources is unacceptable. See Wikipedia:Autobiography, Wikipedia:Notability and Wikipedia:Conflict of interest.
Non-disruptive statements of opinion on internal policies and guidelines may be made on user pages and within the Wikipedia: namespace, as they are relevant to the current and future operation of the project. However, article talk pages should not be used by editors as platforms for their personal views on a subject (see Wikipedia:Talk page guidelines).
is not a mirror or a repository of links, images, or media files
is neither a mirror nor a repository of links, images, or media files. articles are not merely collections of:
External links or Internet directories. There is nothing wrong with adding one or more useful content-relevant links to the external links section of an article; however, excessive lists can dwarf articles and detract from the purpose of. On articles about topics with many fansites, for example, including a link to one major fansite may be appropriate. See Wikipedia:External links for some guidelines.
File storage areas. Please upload only files that are used (or will be used) in encyclopedia articles or project pages; anything else will be deleted. If you have extra relevant images, consider uploading them to the Wikimedia Commons, where they can be linked from.
Dating services. is not an appropriate place to pursue relationships or sexual encounters. User pages that move beyond broad expressions of sexual orientation are unacceptable. However, you very well may form new friendships as you go about improving the encyclopedia.
Memorials. Subjects of encyclopedia articles must satisfy Wikipedia's notability requirements. is not the place to memorialize deceased friends, relatives, acquaintances, or others who do not meet such requirements. (WP:RIP is excluded from this rule.)
Content for projects unrelated to. Do not store material unrelated to, including in userspace. Please see WP:UPNOT for examples of what may not be included.
If you are interested in using the wiki technology for a collaborative effort on something else, even just a single page, many free and commercial sites provide wiki hosting. You can also install wiki software on your server. See the installation guide at MediaWiki.org for information on doing this. See also Wikipedia:Alternative outlets.
Your user page is not yours. It is a part of, and exists to make collaboration amongns easier, not for self-promotion. See Wikipedia:User pages for current consensus guidelines on user pages.
encompasses many lists of links to articles within that are used for internal organization or to describe a notable subject. In that sense, functions as an index or directory of its own content. However, is not a directory of everything in the universe that exists or has existed. Please see Wikipedia:Alternative outlets for alternatives. articles are not:
Lists or repositories of loosely associated topics such as (but not limited to) quotations, aphorisms, or persons (real or fictional). If you want to enter lists of quotations, put them into our sister project Wikiquote. Of course, there is nothing wrong with having lists if their entries are relevant because they are associated with or significantly contribute to the list topic. also includes reference tables and tabular information for quick reference. Merged groups of small articles based on a core topic are permitted. (See Wikipedia:Stand-alone lists § Appropriate topics for lists for clarification.)
Genealogical entries. Family histories should be presented only where appropriate to support the reader's understanding of a notable topic.
The White or Yellow Pages. Contact information such as phone numbers, fax numbers and e-mail addresses is not encyclopedic. Likewise, disambiguation pages (such as John Smith) are not intended to be complete listings of every person named John Smith—just the notable ones.
Directories, directory entries, electronic program guides, or resources for conducting business. For example, an article on a broadcaster should not list upcoming events, current promotions, current schedules, format clocks, etc., although mention of major events, promotions or historically significant program lists and schedules may be acceptable. Likewise an article on a business should not contain a list of all the company's patent filings. Furthermore, the Talk pages associated with an article are for talking about the article, not for conducting the business of the topic of the article.
Sales catalogues. An article should not include product pricing or availability information unless there is an independent sourceand a justified reason for the mention. Encyclopedic significance may be indicated if mainstream media sources (not just product reviews) provide commentary on these details instead of just passing mention. Prices and product availability can vary widely from place to place and over time. is not a price comparison service to compare the prices of competing products, or the prices and availability of a single product from different vendors or retailers.
Non-encyclopedic cross-categorizations, such as "people from ethnic / cultural / religious group X employed by organization Y" or "restaurants specializing in food type X in city Y". Cross-categories such as these are not considered a sufficient basis for creating an article, unless the intersection of those categories is in some way a culturally significant phenomenon. See also Wikipedia:Overcategorization for this issue in categories.
Simple listings without context information. Examples include, but are not limited to: listings of business alliances, clients, competitors, employees (except CEOs, supervisory directors and similar top functionaries), equipment, estates, offices, store locations, products and services, sponsors, subdivisions and tourist attractions. Information about relevant single entries with encyclopedic information should be added as sourced prose. Lists of creative works in a wider context are permitted.
is not a manual, guidebook, textbook, or scientific journal
is an encyclopedic reference, not an instruction manual, guidebook, or textbook. articles should not read like:
Instruction manuals. While has descriptions of people, places and things, an article should not read like a "how-to" style owner's manual, cookbook, advice column (legal, medical or otherwise) or suggestion box. This includes tutorials, instruction manuals, game guides, and recipes. Describing to the reader how people or things use or do something is encyclopedic; instructing the reader in the imperative mood about how to use or do something is not. Such guides may be welcome at Wikibooks instead.
Travel guides. An article on Paris should mention landmarks, such as the Eiffel Tower and the Louvre, but not the telephone number or street address of the "best" restaurants, nor the current price of a café au lait on the Champs-Élysées. is not the place to recreate content more suited to entries in hotel or culinary guides, travelogues, and the like. Notable locations may meet the inclusion criteria, but the resulting articles need not include every tourist attraction, restaurant, hotel or venue, etc. While travel guides for a city will often mention distant attractions, a article for a city should list only those that are actually in the city. If you do wish to help write a travel guide, your contributions would be welcome at our sister project, Wikivoyage.
Video game guides. An article about a video game should briefly summarize the story and the main actions the player performs in the game; however, avoid lists of gameplay weapons, items, or concepts, unless these are notable as discussed in secondary sources in their own right in gaming context (such as the BFG9000 from the Doom series). Walk-throughs or detailed coverage of specific point values, achievements, time-limits, levels, types of enemies, character moves, character weight classes, and so on are also considered inappropriate. A concise summary is appropriate if it is essential to understanding the game or its significance in the industry. See also WP:VGSCOPE.
Internet guides. articles should not exist only to describe the nature, appearance or services a website offers, but should also describe the site in an encyclopedic manner, offering detail on a website's achievements, impact or historical significance, which can be kept significantly more up-to-date than most reference sources, since editors can incorporate new developments and facts as they are made known. See the Current events portal for examples.
FAQs. articles should not list frequently asked questions (FAQs). Instead, format the information as neutral prose within the appropriate article(s).
Textbooks and annotated texts. is an encyclopedic reference, not a textbook. The purpose of is to present facts, not to teach subject matter. It is not appropriate to create or edit articles that read as textbooks, with leading questions and systematic problem solutions as examples. These belong on our sister projects, such as Wikibooks, Wikisource, and Wikiversity. Some kinds of examples, specifically those intended to inform rather than to instruct, may be appropriate for inclusion in a article.
Scientific journals. A article should not be presented on the assumption that the reader is well-versed in the topic's field. Introductory language in the lead (and sometimes the initial sections) of the article should be written in plain terms and concepts that can be understood by any literate reader of without any knowledge in the given field before advancing to more detailed explanations of the topic. While wikilinks should be provided for advanced terms and concepts in that field, articles should be written on the assumption that the reader will not or cannot follow these links, instead attempting to infer their meaning from the text. See Wikipedia:Manual of Style/Linking.
Academic language. Texts should be written for everyday readers, not just for academics. Article titles should reflect common usage, not academic terminology, whenever possible.
Case studies. Many topics are based on the relationship of factor X to factor Y, resulting in one or more full articles. For example, this could refer to situation X in location Y, or version X of item Y. This is perfectly acceptable when the two variables put together represent some culturally significant phenomenon or some otherwise notable interest. Often, separate articles are needed for a subject within a range of different countries, due to substantial differences across international borders; articles such as "Slate industry in Wales" and "Island fox" are fitting examples. Writing about "Oak trees in North Carolina" or "Blue trucks", however, would likely constitute a POV fork or original research, and would certainly not result in an encyclopedic article.
is not a collection of unverifiable speculation or presumptions. does not predict the future. All articles about anticipated events must be verifiable, and the subject matter must be of sufficiently wide interest that it would merit an article if the event had already occurred. It is appropriate to report discussion and arguments about the prospects for success of future proposals and projects or whether some development will occur, if discussion is properly referenced. It is not appropriate for editors to insert their own opinions or analyses. Predictions, speculation, forecasts and theories stated by reliable, expert sources or recognized entities in a field may be included, though editors should be aware of creating undue bias to any specific point-of-view. In forward-looking articles about unreleased products, such as films and games, take special care to avoid advertising and unverified claims (for films, see WP:NFF). In particular:
...but does not.
Individual scheduled or expected future events should be included only if the event is notable and almost certain to take place. Dates are not definite until the event actually takes place. If preparation for the event is not already in progress, speculation about it must be well documented. Examples of appropriate topics include the 2024 U.S. presidential election and 2028 Summer Olympics. By comparison, the 2036 U.S. presidential election and 2044 Summer Olympics or events surrounding the 250th anniversary of the United States of America in 2026 are not appropriate article topics if nothing can be said about them that is verifiable and not original research. Avoid predicted sports team line-ups, which are inherently unverifiable and speculative. A schedule of future events may be appropriate if it can be verified. As an exception, even highly speculative articles about events that may or may not occur far in the future might be appropriate, where coverage in reliable sources is sufficient. For example, Ultimate fate of the universe is an acceptable topic.
Individual items from a predetermined list or a systematic pattern of names, pre-assigned to future events or discoveries, are not suitable article topics, if only generic information is known about the item. Lists of tropical cyclone names is encyclopedic; "Tropical Storm Ana (2021)" is not, even though it is virtually certain that such a storm will occur. Similarly, articles about words formed on a predictable numeric system (such as "septenquinquagintillion") are not encyclopedic unless they are defined on good authority, or genuinely in use. Certain scientific extrapolations are considered to be encyclopedic, such as chemical elements documented by IUPAC before isolation in the laboratory, provided that scientists have made significant non-trivial predictions of their properties.
Articles that present original research in the form of extrapolation, speculation, and "future history" are inappropriate. Although scientific and cultural norms continually evolve, we must wait for this evolution to happen, rather than try to predict it. Of course, we do and should have articles aboutnotableartistic works, essays, or credible research that embody predictions. An article on weapons in Star Trek is appropriate; an article on "Weapons to be used in World War III" is not.
Although currently accepted scientific paradigms may later be rejected, and hypotheses previously held to be controversial or incorrect sometimes become accepted by the scientific community, it is not the place of to venture such projections.
is not a collection of product announcements and rumors. Although includes up-to-date knowledge about newly revealed products, short articles that consist of only product announcement information are not appropriate. Until such time that more encyclopedic knowledge about the product can be verified, product announcements should be merged to a larger topic (such as an article about the creator(s), a series of products, or a previous product) if applicable.
Editors are encouraged to include current and up-to-date information within its coverage, and to develop stand-alone articles on significant current events. However, not all verifiable events are suitable for inclusion in. Ensure that articles are not:
Original reporting. should not offer first-hand news reports on breaking stories. does not constitute a primary source. However, our sister projects Wikisource and Wikinews do exactly that, and are intended to be primary sources. does have many encyclopedia articles on topics of historical significance that are currently in the news, and can be updated with recently verified information.
News reports. considers the enduring notability of persons and events. While news coverage can be useful source material for encyclopedic topics, most newsworthy events do not qualify for inclusion. For example, routine news reporting of announcements, sports, or celebrities is not a sufficient basis for inclusion in the encyclopedia. While including information on recent developments is sometimes appropriate, breaking news should not be emphasized or otherwise treated differently from other information. Timely news subjects not suitable for may be suitable for our sister project Wikinews. is also not written in news style.
Who's who. Even when an event is notable, individuals involved in it may not be. Unless news coverage of an individual goes beyond the context of a single event, our coverage of that individual should be limited to the article about that event, in proportion to their importance to the overall topic. (See Wikipedia:Biographies of living persons for more details.)
A diary. Even when an individual is notable, not all events they are involved in are. For example, news reporting about celebrities and sports figures can be very frequent and cover a lot of trivia, but using all these sources would lead to over-detailed articles that look like a diary. Not every match played or goal scored is significant enough to be included in the biography of a person.
is not an indiscriminate collection of information
To provide encyclopedic value, data should be put in context with explanations referenced to independent sources. As explained in § Encyclopedic content above, merely being true, or even verifiable, does not automatically make something suitable for inclusion in the encyclopedia. articles should not be:
Summary-only descriptions of works. treats creative works (including, for example, works of art or fiction, video games, documentaries, research books or papers, and religious texts) in an encyclopedic manner, discussing the development, design, reception, significance, and influence of works in addition to concise summaries of those works. For more information regarding summaries, see Wikipedia:Manual of Style/Writing about fiction § Contextual presentation.
Lyrics databases. An article about a song should provide information about authorship, date of publication, social impact, and so on. Quotations from a song should be kept to a reasonable length relative to the rest of the article, and used to facilitate discussion, or to illustrate the style; the full text can be put on Wikisource and linked to from the article. Most song lyrics published after 1924 are protected by copyright; any quotation of them must be kept to a minimum, and used for direct commentary or to illustrate some aspect of style. Never link to the lyrics of copyrighted songs unless the linked-to site clearly has the right to distribute the work. See Wikipedia:Do not include the full text of lengthy primary sources for full discussion.
Exhaustive logs of software updates. Use reliable third-party (not self-published or official) sources in articles dealing with software updates to describe the versions listed or discussed in the article. Common sense must be applied with regard to the level of detail to be included.
The University is not engaged in making ideas safe for students. It is engaged in making students safe for ideas. Thus it permits the freest expression of views before students, trusting to their good sense in passing judgment on these views.
may contain content that some readers consider objectionable or offensive—even exceedingly so. Attempting to ensure that articles and images will be acceptable to all readers, or will adhere to general social or religious norms, is incompatible with the purposes of an encyclopedia.
Some articles may include images, text, or links which are relevant to the topic but that some people find objectionable. Discussion of potentially objectionable content should usually focus not on its potential offensiveness but on whether it is an appropriate image, text, or link. Beyond that, "being objectionable" is generally not sufficient grounds for the removal of content. The Wikipedia:Offensive material guideline can help assess appropriate actions to take in the case of content that may be considered offensive.
Some organizations' rules or traditions call for secrecy with regard to certain information about them. Such restrictions do not apply to, because is not a member of those organizations; thus will not remove such information from articles if it is otherwise encyclopedic.
The above policies are about's content. The following relate to's governance and processes.
While's written policies and guidelines should be taken seriously, they can be misused. Do not follow an overly strict interpretation of the letter of policies without consideration for their principles. If the rules truly prevent you from improving the encyclopedia, ignore them. Disagreements are resolved through consensus-based discussion, not by tightly sticking to rules and procedures. Furthermore, policies and guidelines themselves may be changed to reflect evolving consensus.
A procedural error made in a proposal or request is not grounds for rejecting that proposal or request.
Research about's content, processes, and the people involved can provide valuable insights and understanding that benefit public knowledge, scholarship, and the community, but is not a public laboratory. Research that analyzes articles, talk pages, or other content on is not typically controversial, since all of is open and freely usable. However, research projects that are disruptive to the community or which negatively affect articles—even temporarily—are not allowed and can result in loss of editing privileges. Before starting a potentially controversial project, researchers should open discussion at the Village Pump to ensure it will not interfere with's mission. Regardless of the type of project, researchers are advised to be as transparent as possible on their user pages, disclosing information such as institutional connections and intentions.
Some editors explicitly request to not be subjects in research and experiments. Please respect the wish of editors to opt-out of research.
is not a place to hold grudges, import personal conflicts, carry on ideological battles, or nurture prejudice, hatred, or fear. Making personal battles out of discussions goes directly against our policies and goals. In addition to avoiding battles in discussions, do not try to advance your position in disagreements by making unilateral changes to policies. Do not disrupt to illustrate a point.
Every user is expected to interact with others civilly, calmly, and in a spirit of cooperation. Do not insult, harass, or intimidate those with whom you have a disagreement. Rather, approach the matter intelligently and engage in polite discussion. If another user behaves in an uncivil, uncooperative, or insulting manner, or even tries to harass or intimidate you, this does not give you an excuse to respond in kind. Address only the factual points brought forward, ignoring the inappropriate comments, or disregard that user entirely. If necessary, point out gently that you think the comments might be considered uncivil, and make it clear that you want to move on and focus on the content issue. If a conflict continues to bother you, take advantage of's dispute resolution process. There are always users willing to mediate and arbitrate disputes between others.
In large disputes, resist the urge to turn into a battleground between factions. Assume good faith that every editor and group is here to improve—especially if they hold a point of view with which you disagree. Work with whomever you like, but do not organize a faction that disrupts (or aims to disrupt)'s fundamental decision-making process, which is based on building a consensus. Editors in large disputes should work in good faith to find broad principles of agreement between different viewpoints.
Do not use to make legal or other threats against,ns, or the Wikimedia Foundation—other means already exist to communicate legal problems. Threats are not tolerated and may result in a ban.
is a volunteer community and does not require thens to give any more time and effort than they wish. Focus on improving the encyclopedia itself, rather than demanding more from otherns. Editors are free to take a break or leave at any time.
is not any of a very long list of terrible ideas. We cannot anticipate every bad idea that someone might have. Almost everything on this page made it here because somebody managed to come up with some new bad idea that had not been anticipated. (See WP:BEANS—it is, in fact, strongly discouraged to anticipate them.) In general, "that is a terrible idea" is always sufficient grounds to avoid doing something, provided there is a good reason that the idea is terrible.
When you wonder what should or should not be in an article, ask yourself what a reader would expect to find under the same heading in an encyclopedia.
When you wonder whether the rules given above are being violated, consider:
Modifying the content of an article (normal editing).
Turning the page into a redirect, preserving the page history.
Nominating the page for deletion if it meets grounds for such action under the Deletion policy page. To develop an understanding of what kinds of contributions are in danger of being deleted, you have to regularly follow discussions there.
Changing the rules on this page after a consensus has been reached following appropriate discussion with otherns via the Talk page. When adding new options, please be as clear as possible and provide counter-examples of similar, but permitted, subjects.
^"Projects that are "potentially controversial" include, but are not limited to, any project that involves directly changing article content (contributors are expected to have as their primary motivation the betterment of the encyclopedia, without a competing motivation such as research objectives), any project that involves contacting a very large number of editors, and any project that involves asking sensitive questions about their real-life identities.
