Featured Collection: The Valentine/Darwin Collection
In 2007 Dr. James W. Valentine, Professor Emeritus of Integrative Biology at the University of California, Berkeley,
contributed to the Society his collection of nearly 4,500 volumes of the printed works of Charles Darwin in more than
25 languages of the world. The Valentine/Darwin Collection promises to be a trove of information about the ways in
which Darwin’s powerful ideas moved across cultures and through time. Dr. Valentine’s goal was to place the collection,
assembled over 50 years, in a repository where it would have appropriate context, where it would be kept intact as a
collection, and where it would be accessible to scholars. The APS Library, with its vast history of science collections,
including the largest collection of Darwin's manuscripts in North America, was pleased to accept the collection on this basis.
