What I’m writing about can be found at the WikiMedia list of Projects page, but I feel like paying it a tribute here, as it is becoming the greatest repository of content on the Internet.
Wiktionary, the multilingual dictionary in every language
Wikiquote, the compendium of quotations.
Wikibooks, a collection of open-content textbooks. It includes the Wikiversity, the learning community with online courses.
Wikisource, the repository of source texts in any language which are either in the public domain, or are released under the GNU Free Documentation License.
Wikinews, the free-content news source
Wikimedia Commons, the central repository for free images, music, sound & video clips and, possibly, texts and spoken texts, used in pages of any Wikimedia project
Wikispecies, the open, free directory of species
Pretty bunch of content, isn’t it?
It might seem absurd to copy and paste this information here, but I guess some of us did not know about all the projects the WikiMedia Foundation is running untill we bumped into someone posting about them ;)
