Biodiversity Heritage Library

Online catalog of biodiversity materials. "The Biodiversity Heritage Library improves research methodology by collaboratively making biodiversity literature openly available to the world as part of a global biodiversity community... through local digitization efforts, the BHL has digitized millions of pages of taxonomic literature, representing over 100,000 titles and over 170,000 volumes... These collections are of exceptional value because the domain of systematic biology depends, more than any other science, upon historic literature... Free global access to digital literature repatriates information about the earth’s species to all parts of the world." Select culturally specific land and plant management materials are available, as well as documents related to the significance, uses, and traditions associated with local natural environments.
