In 1909, scientists Herbert Lang and James P. Chapin, as well as numerous assistants, set out into the remote Central African Congo River basin to explore and catalog the many extraordinary plant and animal species found within. This fabulous new Web sitefrom the American Museum of Natural History details the six-year expedition that resulted in the first comprehensive study of the Congo basin. This online exhibit includes field notes, photographs, illustrations, interactive maps, and films of early 20th century Congo biological and cultural features. There is also a searchable collection of scientific publications, many of which were authored by Lang, Chapin, and their contemporaries. This is a rich resource that is likely to appeal to many. This site is also reviewed in the March 8, 2002 Scout Report.
