Darwin did a lot of letter writing. I mean a LOT. Nearly 14,500 of his letters exist today. I know we have talked earlier about the Darwin Correspondence Project, which tries to collect all of Darwin's correspondence, but today, all of Darwin's correspondence which has been stored by the Project offline has debuted online. The database contains more than 50,000 pages of text and 45,000 images. The actual letters are housed in University of Cambridge. Maybe we should go?
The website for the database is found here , and an article about the database is found here .
