“Public libraries have always evolved alongside the needs of their communities,” said Mark Fink, Executive Director of Anythink Libraries. “The Nature Library represents the next evolution: a place where books, nature, science and community come together to inspire curiosity and connection. We hope every visitor leaves feeling more connected to the natural world and empowered to continue exploring it long after they leave.”
As libraries across the country continue to evolve into centers for creativity, innovation and community connection, the Nature Library introduces a new model by making environmental exploration a core part of the library experience.
The campus helps remove barriers that often prevent people from connecting with nature by providing welcoming spaces, hands-on learning opportunities and resources that encourage visitors of all ages to explore the outdoors with confidence.
Visitors will discover an art and science lab, gardens, gathering spaces, a living plant wall, immersive sensory environments, a water flow and mud pit and interactive TryIts that encourage exploration on and off the property.
TryIts are experiential kits and equipment that encourage people to continue exploring beyond the library.
Library visitors will have access to approximately 550 items across 65 unique collections, including bird-watching kits, wildlife cameras, hiking gear, microscopes, weather exploration tools, gardening equipment, nature art kits and conservation resources. The collection will continue to grow, with a long-term goal of offering more than 1,500 items.
The Anythink Nature Library is located at 6811 E. 136th Ave. in Thornton.
