Amphibian Species of the World
In 1985, the ASC gave the copyright for Amphibian Species of the World to the Herpetologists' League, and they added more amphibians to it.  The League and American Museum of Natural History put D.R. Frost in charge of the project.  At the time, Frost was a curator at the American Museum of Natural History.  Frost added more information for professional amphibian scientists to use.  He corrected bad information.  He added more species that had been discovered after 1985.
