The Darwin Manuscripts Project is uploading Darwin's original drafts - 10,000 pages worth - into an online archive. The collection includes 34 of the original 36 draft leaves of the book, according to editor David Kohn. "I've sat in the Cambridge University Library since 1974, touching these documents, but this is the first time that anyone can do this online in this quantity and with this quality," Kohn said. The project leaders intend to digitize more manuscripts down the road, and also reconstruct Darwin's library. The Darwin Manuscripts Project is funded by two grants from the National Science Foundation, and a new grant from JISC/NEH Transatlantic Digitization Collaboration program will fund the work to digitally reconstruct Darwin's working library as it stood at the time of his death in 1882.
