Located within the Middle Country Public Library, the Miller Center offers access to extensive and specialized business resources as well as personalized business research and reference assistance. The goal of the Center is to support regional economic development by meeting the information needs of the business community, promoting a literate and job-ready workforce, and providing employment information and career exploration opportunities.

Nature Explorium


Middle Country Public Library is proud to be the first library in the nation to offer the Nature Explorium, an outdoor learning space for children and families. Developed in collaboration with the Dimensions Educational Research Foundation and Long Island Nature Collaborative for Kids (LINCK), the Nature Explorium contains a variety of areas, all geared toward connecting children to a different aspect of nature. Whether they’re reflecting on a poem under a willow tree, climbing on a tree stump, or expressing artistic talent through song and dance on the Play It stage, children will discover the gift of nature. More information on the Nature Explorium can be found here.
