Project Gutenberg, founded in 1971, is the oldest producer and distributor of free ebooks.
According to Michael Hart (March 8, 1947 – September 6, 2011), founder of Project Gutenberg, the mission of Project Gutenberg is simple: to encourage the creation and distribution of eBooks.
This mission is, as much as possible, to encourage all those who are interested in making eBooks and helping to give them away.
