Darwin Online is the largest and most widely consulted edition of the writings of Charles Darwin ever published. It is probably the most extensive scholarly website devoted to any historical figure.
This website contains over 212,000 pages of searchable text and 220,000 electronic images, at least one exemplar of all known Darwin publications, reproduced to the highest scholarly standards, both as searchable text and electronic images of the originals. The majority of these have been edited and annotated here for the first time with more than 4,900 original editorial notes. The pages of documents available only as PDFs have not been counted but they amount to tens of thousands of additional pages of works by Darwin and others.
