The Biodiversity Heritage Library (BHL) is a consortium of natural history and botanical libraries that cooperate to digitize and make accessible the legacy literature of biodiversity held in their collections and to make that literature available for open access and responsible use as a part of a global “biodiversity commons.” BHL also serves as the foundational literature component of the Encyclopedia of Life (EOL). BHL content may be freely viewed through the online reader or downloaded in part or as a complete work in PDF, OCR text, or JPG2000 file formats.
There are currently more than 54,000 titles and 103,000 volumes that can be browsed or searched, together covering over 1,060,000 species.
