NPR New 'Letters from Mississippi' Addresses Omissions: The book Letters from Mississippi documented the experiences of volunteers who moved to the South during the summer of 1964 to register black voters and work in what were called freedom schools. Published in 1965, it was out of print a year later, dismissed by many of the volunteers who were embarrassed that it only included the experiences of white kids. A new edition has just been published — with an introduction by Julian Bond — that addresses the earlier omissions.
