Peter Baldwin, Lisbet Rausing give an additional $3.5 million to the Wikimedia Endowment24 April 2019
Three years ago, we created the Wikimedia Endowment as a permanent, independent fund dedicated to ensuring the long-term sustainability of Wikipedia and the other Wikimedia free knowledge projects. In other words, it will help sustain Wikipedia for decades to come. But the Endowment is not a simple undertaking. It relies on the generosity of donors….
Notre Dame will live on—but that won’t be the case for all our cultural landmarks23 April 2019
Last week, I watched, completely helpless, as the spire of Notre-Dame de Paris was eaten away by a blazing fire. I lived for seven years in France’s capital.

Throughout history, knowledge has been controlled by a powerful few. Wikipedia needs knowledge from all languages and cultures.

KEY INFORMATION — معلومات أساسية
Things to know
Wikimedia projects belong to everyone
We respect your data
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 others can help.
Not all wikis are Wikimedia
The word “wiki” refers to a website built using collaborative editing software. Hundreds of organizations and projects with no affiliation with Wikipedia or the Wikimedia Foundation also use the term, including wikiHow and WikiEducator.
Wikimedia has nothing to do with Wikileaks and never did. Although both use the term “wiki” in their name, they have always been completely separate and unaffiliated.
Help us unlock the world’s knowledge.
As a nonprofit, Wikipedia and our related free knowledge projects are powered primarily through donations.Donate
