The Freedom Summer of 1964 helped usher in civil rights laws for black Americans.
But the price was steep: many people of many ethnic backgrounds gave up their security and even their lives for civil rights.
Their efforts are not only remembered, but documented extensively.
A companion to the civil rights efforts was the Southern Documentary Project, which scattered reporters and photographers around the South to record the events for the major picture magazines.
Matt Herron directed the project, which gains a new audience through his book Mississippi Eyes.
