WikiZnanie (ВикиЗнание) is a Russian language WikiWiki encyclopedia released under the FreeBSD Documentation License license and created in 2003. It uses the MediaWiki software. The name derives from wiki and znanie, which is Russian for knowledge.
In 2006, WikiZnanie added over 1000 articles. As of July 2008, WikiZnanie has over 111,000 articles (compared with over 297,000 on the Russian Wikipedia). The main part (about 95-98%) of its content comes from Brockhaus and Efron Encyclopedic Dictionary, which was published in Imperial Russia in 1890-1906.
WikiZnanie differs from the Wikipedia (and Russian Wikipedia) project by licensing under the BSL DPL (instead of GFDL) and displaying of commercial ads on article pages. It also allows original research (which must, if possible, use the methodology of scientific research) and encourages "multiple points of view" rather than "neutral point of view" in articles. It has servers in Moscow for faster access to pages from Russian territory and uses ads to secure financial support.
The author and webmaster of the project is Andrey Vovk ().
