ZSL Prince Philip Library and Archives

The Zoological Society of London was formed in 1826, and since that time we have maintained a world-leading library and archive which has helped generations of leading zoologists, scientists and conservationists understand the natural world.

Scientific events and public engagement 

Communicating science is an important part of our work. We are in a unique position to engage with over 1.7 million people visiting ZSL’s Zoos annually. Our public engagement activities help us to understand how people relate to the ways in which science can provide solutions to global environmental challenges.

We inspire and inform people about wildlife and its conservation. Engaging members of the public from all areas, including those from underserved and underrepresented communities, is vital to communicating our work. Public engagement projects include Refugia, Scientist in Your Classroom and Soapbox Science.
