In another thread, Nigel Parsons gave a link to an obituary in the Daily Telegraph 22 July 2002
This is the longer thread so I am repeating the link here

I read an obit. in the Observer on Sunday (UK) which was more detailed than the Telegraph article, about Lomax collecting blues, about his difficulties during the McCarthy era of persecuting artists for alleged Communist sympathies, and about his years collecting songs in the British Isles. The Observer article also referred to the NY Times obit, which I expect is available on line to those who register at the NY Times website.
