Darwin Correspondence Project

For nearly fifty years successive teams of researchers on both sides of the Atlantic have been working to track down all surviving letters written by or to Charles Darwin, research their content, and publish the complete texts. The thirtieth and final print volume, covering the last four months of Darwin’s life, will be published in early 2023 and all the letter texts – more than 15000 between 1822 and 1882 – are now published online. Discover more about the final months of Darwin's life in our Life and Letters series, 1882: Nothing too great or too small. See a full list of letters from 1882.

In October 1881, Darwin published his last book, The formation of vegetable mould through the action of worms: with observations on their habits. A slim volume on a subject that many people could understand and on which they had their own opinions, it went through several reprints within a year. The idea of the powerful effects brought about by apparently insignificant creatures caught the public imagination. Read more about Darwin's life in 1881 and see a full list of letters.
