This Sourcebook has been compiled to provide those concerned with conservation and biological diversity with a guide to expertise and information. It is hoped that it will help build bridges between individuals and organizations; helping all of us to maximize existing sources of expertise and information. The Sourcebook is a kind of 'road map" to key organizations, resources, data and services. The sources covered are: organizations, books, periodicals, multi-media CD-ROMs, video films, commercial databases available online or as packaged products (typically in CD-ROM format), and public-access information available over the Internet.
