Under the leadership of Sadie Harrison, who at the time was the Secretary of The Negro Welfare Council (also known as the Negro Urban League), Hackley & Harrison's Hotel and Apartment Guide for Colored Travelers was published in 1930 in response to the growing number of African Americans who were purchasing and traveling by automobile. An interesting fact about Hackley & Harrison's is that on one of the first pages, there is a letter to the editor asking about a colored boarding house in New London by W.E.B. Du Bois.
