The "Green Book," officially titled "The Negro Motorist Green Book," was a vital travel guide for African Americans during the years 1936 to 1966 in the United States. It listed establishments such as hotels, motels, restaurants, gas stations, and other services that were safe and welcoming to Black travelers during a time of widespread racial segregation and discrimination. These establishments were often referred to as "Green Book businesses." They provided essential information, enabling Black travelers to plan their journeys, avoid areas with heightened racial hostility, and find places where they could receive basic services and accommodations without fear of racial discrimination or violence.
