Darwin on-line

Rare material on the site includes text from Darwin's Galapagos notebook; the original was stolen in the 1980s, but a copy had been made in the 1960s. Currently, about 50% of Darwin's work is available - it is planned to complete the project by 2009, the bicentenary of Darwin's birth.

The site includes German, Danish and Russian editions.
