Atlanta Central Library & Library System Headquarters, Main library in downtown Atlanta, US.

Atlanta Central Library serves as the headquarters of the Fulton County Library System, housing multiple floors of books, periodicals, digital resources, and research materials across different subject areas. The building organizes these collections and services into distinct zones for various research and learning needs.

The first public library on this site, a Beaux-Arts Carnegie Library designed by Ackerman & Ross, opened on March 4, 1902, with only its foundation, stacks and children's room finished. It served as the system's main library for most of the century, gained an annex in 1935 and an expansion in 1950, and was demolished in 1977. Marcel Breuer's replacement, dedicated on May 25, 1980, was his last completed building; a full renovation ran from 2018 to 2021 after a 2016 vote rejected demolition.

The library maintains collections reflecting Atlanta's diverse communities, including genealogy resources and materials about local heritage and traditions.

The library occupies a full city block bounded by Fairlie, Williams, Forsyth and Carnegie Way, with its main facade on Forsyth Street facing Margaret Mitchell Square. The entrance is on that side, across from the Georgia-Pacific Tower. It opens six days a week, Tuesday to Saturday from 10 a.m. to 6 p.m. and Monday until 8 p.m., and is closed on Sundays; holiday hours change, so check before visiting.

The Carnegie Library that stood here until 1977 was not fully lost: some of its column bays were reused to build the Carnegie Education Pavilion, a monument to higher education in Atlanta. The 1980 building's concrete facade was shaped with recessed, windowed niches because concrete made that form the cheapest option.
