The Library of Congress and other government agencies join forces every February to present a Web site celebrating African American History Month.
This year the Web site includes an online exhibition commemorating two landmark events in African Americans' struggle for freedom: the Emancipation Proclamation (1863) and the March on Washington (1963).
Below is an image from the exhibition, a flyer calling participants from Virginia to the March on Washington.
