The Biodiversity Heritage Library is the world’s largest open-access digital archive dedicated to life on Earth. It is comprised of animal sketches, historical diagrams, botanical studies, and various scientific research collected from hundreds of thousands of journals and libraries around the globe.
Since 2011, this library has been building an archive on Flickr. By allowing users to gain access to these images, they’re helping us understand how nature has been depicted throughout history. At least 150,000 incredible illustrations are available for free download in high-resolution files thanks to the Biodiversity Heritage Library.
