4th Floor

The 4th floor is a public laboratory and educational facility with a focus on information, design, technology, and the applied arts. The more than 12,000 sq foot space hosts equipment, expertise, programs, events, and meetings that work within this scope. While traditional library spaces support the consumption of knowledge by offering access to media, the 4th floor is unique because it supports the production, connection, and sharing of knowledge by offering access to tools and instruction.

Donate to the Chattanooga Public Library Foundation to help support services like The 4th Floor and The Studio.
