For scholars, Charles Darwin’s marginalia has offered clues to his evolution as a thinker.
Now with the digitization of his personal library, the English naturalist’s notes and scribbles are being made available online for the first time, reports the University of Cambridge, whose library holds most of Darwin’s collection.
Cambridge is a partner in the digitization project along with the Darwin Manuscripts Project at the American Museum of Natural History; the Library of the Natural History Museum (London); and the Biodiversity Heritage Library.
Darwin’s 1,480-book library included 730 titles with copious research notes in their margins. In the completed first phase of the digitization process, 330 heavily annotated books can be perused, giving readers, says Cambridge, a direct view of the “Darwinian intellectual machine in action.”
The annotations have a separate search mechanism—a key word or phrase will bring up an image of the page so that one can witness the naturalist as reader in all his underscoring vehemence. Consider, for example, this comment on Charles Lyell’s claim, in Principles of Geology, that there were limits on species variations. “If this were true,” thunders Darwin in the margins, “adios theory.”
