The Biodiversity Heritage Library's Digital Treasure Trove

The Biodiversity Heritage Library (BHL) has made over 64 million pages of scientific knowledge freely available online, providing a digital treasure trove for fans of the natural world. The library, which was created 20 years ago, features contributions from over 680 museums, universities, and scientific institutions worldwide.

The Significance of the BHL

The BHL is an invaluable resource for scientists, researchers, and the general public, offering a vast array of historical and scientific content, including published biodiversity literature and journals, letters, illustrations, climate records, field diaries, ecosystem profiles, distribution records, and manuscripts.

Highlights of the BHL Collection

  • The oldest book in the collection is the Circa instans, a medieval pharmacopeia dating back to approximately 1190.
  • An 1892 illustrated exhibition catalogue by Henry Howell & Co, a Victorian firm based in London, which marketed itself as the world’s largest manufacturer of walking sticks.
  • The botanist Sir Joseph Hooker’s illustrated Antarctic journal, which includes his watercolour sketches of two volcanoes, first sighted in 1841 on his expedition to the continent with Capt James Clark Ross.

The Impact of the BHL

The BHL has had a significant impact on scientific research, with historical journals uploaded to the library helping scientists to show that there had been a “massive change” in the distribution and abundance of rare Australian orchids during the “black summer” of the wildfires, in late 2019 and early 2020.

The Future of the BHL

The BHL continues to grow and evolve, with new content being added regularly. The library is an essential resource for anyone interested in the natural world and will continue to play a crucial role in scientific research and discovery for years to come.
