Charles Darwin’s Address Book is a small brown leather notebook, with “VISITS” and “ADDRESSES” printed on its spine (photo 1) and index-letter tabs in alternating black and red. The entries were begun by his wife, Emma Darwin, and are in her pleasant, rounded handwriting (photo 2), shortly after their marriage in January 1839. Latter entries were by Darwin (photo 3), and he continued to use this Address Book throughout his lifetime.
