Ten major natural history museum libraries, botanical libraries, and research institutions have joined to form the Biodiversity Heritage Library Project. The group is developing a strategy and operational plan to digitize the published literature of biodiversity held in their respective collections. This literature will be available through a global "biodiversity commons."
* American Museum of Natural History (New York, NY)
* The Field Museum (Chicago, IL)
* Harvard University Botany Libraries (Cambridge, MA)
* Harvard University, Ernst Mayr Library of the Museum of Comparative Zoology (Cambridge, MA)
* Marine Biological Laboratory / Woods Hole Oceanographic Institution (Woods Hole, MA)
* Missouri Botanical Garden (St. Louis, MO)
* Natural History Museum (London, UK)
* The New York Botanical Garden (New York, NY)
* Royal Botanic Gardens, Kew (Richmond, UK)
* Smithsonian Institution Libraries (Washington, DC)
The participating libraries have over two million volumes of biodiversity literature collected over 200 years to support the work of scientists, researchers, and students in their home institutions and throughout the world. The 10 member libraries of the Biodiversity Heritage Library (BHL) members now have over 1.124 million pages of key taxonomic literature available on the web.
The BHL will provide basic, important content for immediate research and for multiple bioinformatics initiatives. For the first time in history, the core of our natural history and herbaria library collections will be available to a truly global audience. Web-based access to these collections will provide a substantial benefit to people living and working in the developing world -- whether scientists or policymakers.
