Let me congratulate Andree for having done this. My attitude is that the more mathematics is freely available online, the more the profession will benefit. That is why all my own papers that I can find online (many the result of McGill's subscription and not generally available) can be found at ftp.math.mcgill.ca/pub/barr/pdffiles. I am, of course, violating copyrights in doing so, so sue me. I will add my Cahiers papers to the collection as soon as I have time. Michael On Sun, 25 May 2008, Andree Ehresmann wrote:

I am pleased to inform you that all the former volumes of the "Cahiers" are now freely available on the NUMDAM site: http://www.numdam.org/numdam-bin/feuilleter?j=CTGDC (for volumes from VIII to XLVII (2006) and http://www.numdam.org/numdam-bin/feuilleter?j=SE (under the title "Seminaire Ehresmann") for Volumes I to VIII. From now on, all the papers will be so available less than 2 years after the printed publication.

Hoping this will be useful for readers and authors,

Sincerely Andree C. Ehresmann
