Darwin's Library is a special digital reconstruction of the working library of Charles Darwin, drawn from Darwin's own copies held at Cambridge University Library. Our iTunes U selection includes some of the most significant and highly annotated books on Darwin's shelves, all digitized from the originals at Cambridge. The Darwin's Library project was funded by the JISC and the National Endowment for the Humanities, worked on in collaboration with the Darwin Manuscripts Project at the American Museum of Natural History, and undertaken with the permission of the Darwin estate. The materials made available through iTunes U are available for non-commercial use.
