"The Correspondence of William Henry Fox Talbot Project has 
prepared a comprehensive edition of the nearly 10,000 letters to and 
from Talbot (1800-1877), the Wiltshire polymath best known for his 
invention of photography. Draft transcriptions of nearly all the letters
 were posted by September 2003 and these are now being further annotated
 and edited."
