Wikipedia is a collaborative, multilingual online encyclopedia consisting of freely editable articles written and maintained primarily by volunteers worldwide, utilizing wiki software to enable open contributions under free content licenses. Launched on January 15, 2001, by American entrepreneur Jimmy Wales and philosopher Larry Sanger as a wiki-based complement to the slower-paced expert-reviewed Nupedia project, it rapidly expanded due to its accessible editing model.[1][2] Since 2003, Wikipedia has been hosted and supported by the Wikimedia Foundation, a non-profit organization that provides technical infrastructure and promotes free knowledge dissemination.[3] As of October 2025, Wikipedia encompasses over 65 million articles across 357 language editions, making it one of the largest reference works ever compiled, with the English edition alone surpassing 7 million entries.[4] Renowned for its unprecedented scale, accessibility, and role in democratizing information, Wikipedia has nonetheless encountered persistent criticisms regarding factual reliability, susceptibility to vandalism and hoaxes, and systemic ideological biases—particularly a left-leaning slant in coverage of political figures and topics, as evidenced by computational analyses associating right-of-center entities with more negative sentiment and acknowledged by co-founder Sanger who has described the platform as captured by ideologically driven editors.

Overall I think I'd read the Wikipedia one on the whole.
