The Biodiversity Heritage Library (BHL) aims to digitize the core published literature on biodiversity and make it openly accessible online. It works with the global taxonomic community and rights holders. The BHL has begun scanning over 400,000 volumes from several founding institution partners. Its goals are to provide global access to biodiversity literature, which will change how taxonomists work, and to support projects like the Encyclopedia of Life. The BHL costs an estimated $20-30 million to complete and has raised around $12.5 million so far.
