This grant to the Wikimedia Foundation provides continued administrative and operational support for Wikipedia, the fifth largest website in the world and the largest encyclopedia in history.  Over the next five years, grant funds will be used in a series of projects to bolster Wikipedia’s technical infrastructure, improve editor engagement, increase the number of women editors, increase the number of contributions via mobile devices, better integrate multimedia offerings such as video, audio, and photography into Wikipedia pages, and help Wikipedia improve and monitor article quality while moving toward self-sustainability.
