Biodiversity Heritage Library

The Biodiversity Heritage Library (BHL) is the world’s largest open access digital library for biodiversity literature and archives. BHL is revolutionizing global research by providing free, worldwide access to knowledge about life on Earth. BHL operates as a worldwide consortium of natural history, botanical, research, and national libraries working together to address this challenge by digitizing the natural history literature held in their collections and making it freely available for open access as part of a global “biodiversity community.” The BHL portal provides free access to hundreds of thousands of volumes, comprising over 60 million pages, from the 15th-21st centuries.
