Victor Green, a postal worker from Harlem, began publishing the Green Book in 1936. It was a state-by-state guide to hotels, restaurants, nightclubs, gas stations and popular sights that welcomed African-American travelers and tourists in a time of racial segregation.
University of South Carolina's South Caroliniana Library holds a spring 1956 Green Book in its collections, which is on display through the spring 2019 semester at Thomas Cooper Library in Columbia, SC.
