Tina has just pointed out to me that the "Book Of The Week" in the Review section of The Guardian today is a glowing account of "The Man Who Recorded the World: A Biography of Alan Lomax" by John Szwed. It is online at http://www.guardian.co.uk/books/2011/jan/08/alan-lomax-john-szwed-review?INTCMP=SRCH . Shirley Collins' book, America Over The Water also gets a favourable mention.
