Ronald D. Cohen has performed an invaluable service in gathering together Alan Lomax's letters, from many scattered sources and under difficult circumstances, covering Lomax's most active period at the Library of Congress, from 1935 to 1945. Alan Lomax, following in the footsteps of his father, pioneer folksong collector John Lomax, became the preeminent authority on the indigenous music of the world. From the time he was seventeen until his death in 2002 at age eighty-seven, he was indefatigable in recording and documenting the folksongs, folk tales, and folk customs of both North America and Western Europe. Like his father, he was a prodigious letter-writer, and his correspondence provides a detailed and most interesting account of his day-to-day activity.--Nolan Porterfield, author of Last Cavalier: The Life and Times of John A. Lomax
