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.” 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. http://www.biodiversitylibrary.org/
