The Biodiversity Heritage Library (BHL) is a global consortium of natural history and botanical libraries working to digitize biodiversity literature and make it openly accessible online. It includes various regional BHL programs around the world. The BHL aims to ensure long-term access to its digital collections by maintaining content across different locations, administrations, and technologies. It also provides open data and software through various online resources. The future of BHL includes expanding its online content, adding new partners and regions, and exploring challenges around electronic publishing.
