“The Negro Motorist Green Book,” a guide for African Americans first published in 1936, was a valued resource at a time when travel held the promise of adventure, but was also perilous.

It is now the subject of an exhibit here at the Martin Luther King Jr. Memorial Library in Washington, D.C.,

Candacy Taylor, who wrote “Overground Railroad: The Green Book and the Roots of Black Travel in America,” helped pull the exhibit together with the Smithsonian Institution Traveling Exhibition Service and the D.C. public library system.

The exhibit tells the history of the guide named after its creators, Victor Hugo Green and his wife, Alma.
