Frequently asked questions
This page lists frequently asked questions about the Wikimedia Foundation. Other questions are addressed at Answers. If you do not find your question answered here or there, please feel free to contact us.
What is Wikipedia?
Wikipedia is an online collection of knowledge. Volunteer editors from around the world write Wikipedia. It is a collaborative creation created in 2001: anyone can edit it, at any time. Editors collaborate to write about virtually any topic, from ancient history to science to the arts. Wikipedia is available in hundreds of languages and has over 45 million articles. Wikipedia is completely non-profit, independent, and maintained by everyday people like you. You do not require approval or special qualifications to edit.
How does Wikipedia maintain reliability and neutrality?
Wikipedia's volunteer contributors use reliable sources to support information included in Wikipedia articles, so readers can explore the sources that verify the facts. In order for content to remain on Wikipedia, it must be written from a neutral point of view and attributed to a reliable source. Volunteers collaborate openly and use a variety of mechanisms like bots and monitoring tools to regularly review edits made to Wikipedia and ensure they meet content standards. Wikipedia is based on an open model, so its content is constantly evolving, growing, and improving over time. Unfortunately, vandalism of Wikipedia articles does occasionally occur. However, the vast majority of editors contribute in good faith and most vandalism on the site is removed quickly, often within minutes, by volunteers.
What is the Wikimedia Foundation?
The Wikimedia Foundation is the nonprofit organization that supports Wikipedia, the other Wikimedia free knowledge websites, and its mission of free knowledge for all. We do this by keeping the Wikimedia sites fast, secure, and available to all, defending Wikipedia and our volunteer editors from legal threats, building new features and tools to make it easy to read, edit, and share knowledge from Wikimedia sites, and by supporting the communities of editors who contribute to Wikipedia and the Wikimedia sites. We also help bring new knowledge online, lower barriers to access, and make it easier for everyone to share what they know.
The Wikimedia Foundation is a 501(c)(3) tax-exempt nonprofit organization with offices in San Francisco, California, USA.
What are the other Wikimedia free knowledge projects you support?
In addition to Wikipedia, the Wikimedia Foundation supports a number of free knowledge projects, including:
- Wikimedia Commons – a freely-licensed repository of images, video, and media files
- Wiktionary – a free, multilingual dictionary
- Wikiquote – a resource of quotations from notable people and creative works
- Wikibooks – a collection of books which includes annotated texts, instructional guides, textbooks, and more
- Wikisource – a collection of primary source materials, as well as translations of source texts
- Wikispecies – a species directory, which covers Animalia, Plantae, Fungi, Bacteria, Archaea, Protista and other forms of life
- Wikinews – a collaborative news resource, where anyone can contribute reports about events around the world
- Wikiversity – an educational repository devoted to learning resources, learning projects, and research for use in all levels of education
- Wikidata – a collaborative, multilingual structured database which powers information used across Wikimedia projects
- Wikivoyage – a travel information guide for locations around the world
- MediaWiki – the open source software behind all Wikimedia websites

Is Wikipedia, or the Wikimedia Foundation, affiliated with WikiLeaks?
Wikipedia and the Wikimedia Foundation have no affiliation with WikiLeaks. Although both use the term "wiki" in their name, they have always been completely separate and unaffiliated projects.
Why are there no ads on Wikipedia?
We are not considering advertising as a source of revenue. We do not believe that advertising belongs in a project devoted to free, reliable, and neutral knowledge. Introducing commercial interests could jeopardize Wikipedia’s reliability as a neutral source of information.
We are not against online advertising, nor are we against other organizations that host ads. We just know ads are not appropriate in a project devoted to education and knowledge – and especially one that strives for balance and neutrality.
Where can I find more financial information?
The Wikimedia Foundation's 2016 - 2017 annual report covers the fiscal year from 1 July 2016 to 30 June 2017. The Foundation's annual report shares some of the voices of the hundreds of thousands of people who make the Wikimedia movement possible.
The Wikimedia Foundation 2017-2018 Annual Plan describes our budget for the current fiscal year. It contains a summary of our strategic goals as an organization, financial details on spending and revenue, and detailed explanations and risk analysis.
What is the Wikimedia Endowment?
The Wikimedia Endowment was created in 2016 to support and sustain Wikipedia and the Wikimedia projects for generations to come. Donations to the Wikimedia Endowment are used and maintained in a separate fund that is managed by Tides Foundation and overseen by an independent Advisory Board. Donations to the Wikimedia Endowment are separate from reader donations we receive from banners that appear on Wikipedia. You can learn more about the Wikimedia Endowment here.
What are the plans for Wikimedia's future? Where are you going?
At the beginning of 2017, the Wikimedia Foundation launched a global discussion to define the future of Wikipedia and the Wikimedia movement by the year 2030. We call it Wikimedia 2030. Throughout the process, we asked ourselves questions like, where might we want Wikipedia, and the Wikimedia movement, to go next? What opportunities and challenges lie ahead of us? What trends in technology, education, information, and access will shape our future?
Based on this discussion and our research, we are uniting around a direction that will help us build a more sustainable, resilient, and engaged movement that anyone who shares our vision can join. We will adapt to the shifting trends in technology, to ensure we meet the needs of our users and continue to provide reliable, transparent, and neutral information. We will invite new voices to join us and ensure that anyone who wants to share knowledge on Wikipedia and the Wikimedia sites can do so. And we will advocate for the policies and values that have allowed Wikipedia and its sister sites to thrive. This direction asks us to be bold and experiment in the future, as we did in the past, and it remains rooted in our mission of free knowledge for all.
