This website is part of the Biodiversity Heritage Library and is a virtual reconstruction of the surviving books owned by Charles Darwin. The project aims to digitize the works owned by Darwin, but also to digitize and make accessible the marginalia and other associated notes in this collection.
Darwin's correspondence provides an invaluable source of information, not only about his own intellectual development and social network, but about Victorian science and society in general. They provide a remarkably complete picture of the development of his thinking, throwing light on his early formative years and the years of the voyage of the Beagle, on the period which led up to the publication of The Origin of Species and the subsequent heated debates.
This is a useful Web site for presenting integrated data to students on evolutionary change through time, and is an excellent instructional resource for teachers of grades 8-12 through upper-level undergraduate courses.
This site contains Darwin's complete publications, 20,000 private papers, the largest Darwin bibliography, manuscript catalog and hundreds of supplementary works: specimens, biographies, obituaries, reviews, reference works and much more.
Wallace Online is the first complete edition of the writings of naturalist and co-founder of the theory of evolution Alfred Russel Wallace. Including a comprehensive compilation of his specimens - much of it never before seen. The project is directed by John van Wyhe, assisted by Kees Rookmaaker, at the National University of Singapore, in collaboration with the Wallace Page by Charles H. Smith.
