1
Wikimedia projects belong to everyone
You made it. It is yours to use. For free. That means you can use it, adapt it, or share what you find on Wikimedia sites. Just do not write your own bio, or copy/paste it into your homework.
2
We respect your data and privacy
We do not sell your email address or any of your personal information to third parties. More information about our privacy practices are available at the Wikimedia Foundation privacy policy, donor privacy policy, and data retention guidelines.

People like you keep Wikipedia accurate
Readers verify the facts. Articles are collaboratively created and edited by a community of volunteers using reliable sources, so no single person or company owns a Wikipedia article. The Wikimedia Foundation does not write or edit, but you and everyone you know can help.
4
Not all wikis are Wikimedia
The word “wiki” refers to a website built using collaborative editing software. Projects with no past or existing affiliation with Wikipedia or the Wikimedia Foundation, such as Wikileaks and wikiHow, also use the term. Although these sites also use “wiki” in their name, they have nothing to do with Wikimedia.
Research
We conduct our own research and partner with researchers worldwide to address change in society and technology.

Collaborative projects are the core of the Wikimedia movement
Our volunteers build tools, share photos, write articles, and are working to connect all the knowledge that exists.

Closing the gender gap: Women in Red’s efforts to add more women to Wikipedia
All of the information found on Wikipedia is created and shared by volunteers around the world. However, since 2020, only 15% of these contributors are women. This imbalance has a real impact on how information is covered and presented on the world’s largest online encyclopedia. This problem is often called the “gender gap” and is….

Kelly Doyle Kim and this new Smithsonian museum are writing women into Wikipedia
It’s called the ‘great man theory‘: the idea that large swaths of human history can be explained by the actions of so-called great men. These days, that theory has been resoundingly discredited—but popular history’s long reliance on it has contributed towards an imbalance of stories told about women in the history learned in schools and….

Editor since 2007, Wikimedia communityThroughout history, knowledge has been controlled by a powerful few. Wikipedia needs knowledge from all languages and cultures. The internet has become the default for accessing information—women, people of color, and the global south remain underrepresented. We invite you to help correct history.
Help us unlock the world’s knowledge.
As a nonprofit, Wikipedia and our related free knowledge projects are powered primarily through donations.
