Hi, Susan-
I linked to the last update of the Folktrax Website that is available at archive.org, the Internet Archive Wayback Machine. You can find all archived copies of the Folktrax Website at http://web.archive.org/web/*/http://www.folktrax.org, but some copies are incomplete.
The Website was always hard to read and interpret, but it did contain valuable information once you figured out how to read it. Peter Kennedy switched to the purple format sometime between April and November, 2005. He died 10 June 2006. The last edition of the Website at archive.org is dated 28 Sept 2007, but I suspect that's the last date it was archived by archive.org - not the last date the actual Folktrax Website was updated. The Folktrax Website was taken offline several months after Peter's death. Malcolm Douglas said above that there is thought of resurrecting the Website as a memorial to Peter, but that hasn't happened.

That last archived copy of the Folktrax Website says the Folktrax label ceased operations on 30 September, 2007, after the death of Peter Kennedy's widow, Beryl. Peter Kennedy's Folktrax recordings were to be available for listening at the British Library Sound Archive - but I don't think they're available online. Does Dick Greenhaus still have them available for sale at CAMSCO?
