The University of Cambridge has just posted the complete works of Charles Darwin online. It’s a very interesting site, filled with more than just the text of his important works. From their site: “This site currently contains more than 50,000 searchable text pages and 40,000 images of both publications and handwritten manuscripts. There is also the most comprehensive Darwin bibliography ever published and the largest manuscript catalogue ever assembled. More than 150 ancillary texts are also included, ranging from secondary reference works to contemporary reviews, obituaries, published descriptions of Darwin’s Beagle specimens and important related works for understanding Darwin’s context.”
“Many of the scanned books provided here belonged to Darwin’s family or are signed by him.” I’ve already enjoyed looking at an 1845 edition of his book The Voyage of the H.M.S. Beagle. You will also find many audio files as well. A wonderful online treasure of material.
