The 57 items included in the catalog are each described in some detail, including information on authors, illustrators and illustrative processes, publication, and sources for the work. Each example is accompanied by several excellent images, usually a detail from the work. The catalog includes a wide range of works, covering the usual botany and zoology as well as the emerging fields of what we now know as geology, paleontology, and biogeography. The final section includes Darwin's pre-Origin publications, as well as earlier works postulating some elements of evolutionary processes.
A colorful, vibrant compilation.
