Launched in 2006 and covering the 15th-21st centuries, the Biodiversity Heritage Library (BHL) is the world’s largest open access digital library for biodiversity literature and archives. The BHL operates as a worldwide consortium of natural history, botanical, research, and national libraries working together to digitize 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 makes use of the Global Names Recognition and Discovery (GNRD) service, indexing the taxonomic names throughout its collections, allowing researchers to locate publications about specific taxa.
