Partly, I am responding to this to train my mailer, but also some information.

After Marta Bunge her web site disappeared.  I wrote to our chairman a month ago asking if this was department policy and would mine disappear when I did.  He has not bothered to respond so I guess I know the answer.  The site is math.mcgill.ca/barr<https://protect-au.mimecast.com/s/K9pPCvl1g2S1ZoK5tQsH-q?domain=math.mcgill.ca> and it contains essentially all my published papers and books including the two with Charles.  There is one new thing added: my original thesis, retyped.  It is really mainly of historical interest.  The main result is the direct construction of the shuffle idempotents in dimensions 2,3,4.  Since a later paper found an inductive definition for all n, this is probably not interesting.

Any idea why Mount Alison shut down the list?  Computer storage is so cheap these days it hardly seems worth the effort.
