Digitized Green Books from the New York Public Library
I've just learned this exciting news - Jim Crow era Green Books are now available in digitized form courtesy of the New York Public Library Schomburg Center for Research in Black Culture - a fine institution to be sure. Green Books were travel guides for black families traveling through the segregated nation. By the 1940s, the guides included the mid-Atlantic, the South, The Midwest, and the West Coast. The books provided information on establishments such as hotels and restaurants that catered to black folks - and thus people were able to avoid confrontations with the proprietors of "white only" establishments.
