Dr. Vanessa Tyler talks with Karen Taylor, founder and Executive Director of 'While We Are Still Here', an organization dedicated to preserving the history of Harlem, NY. The group has an initiative called the 'Signs Of The Times: Harlem Markers Project' where they are installing historic markers around the city to honor events, people and organizations vital to the city of Harlem. Future plans include developing a tourist app, where people can walk the city and the app will show the historical significance of each marker.
