Our Vision: 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.

Friday + Saturday 12pm-6pm.

GigLab Launches on the 4th Floor

GigLab offers public access to gigabit connectivity in Chattanooga at the Public Library

The Chattanooga Public Library has been a part of the city’s gigabit ecosystem and infrastructure since 2012, when the 4th Floor became the first public library space in the United States to offer access to a full gig of speed. Now with GigLab the general public will have access to enterprise-level gigabit connected hardware,  plus short-session and hands on courses on networking, and other gigabit focused projects. Check out PHOTOS from launch day!
