I have redone my ftp site to a certain extent. Available now are the latest version of TTT (a small number of corrections, plus one place where some incomprehensible equations were replaced by equivalent diagrams) and a couple of my older papers that I found on Jstor. I really do not understand the copyright issues on the latter. Clearly Jstor deserves something (but they earned a fee when I downloaded them). In the olden days (say 25 years ago and older) the publishers did not ask for any copyright form signed, but just registered a copyright. They act as if I have no rights, but I believe that without a piece of paper, they cannot really stop me. I have not signed over my rights since before 1995 (including two papers in 1995 in JPAA, where I gave them only a right-to-print). So there is a ten or 15 year period where I really did sign over the copyright. So be warned. Incidentally, Charles and I have full rights to TTT and this is posted with Charles's permission. My ftp site is ftp.math.mcgill.ca/pub/barr/pdffiles Michael
