Diagammes, Ehresmann Supplements to Cahiers

With the recent question about references for sketch theory in mind, perhaps now is a good time to ask: Are the old issues of Diagrammes available anywhere on the web? Also, although the regular issues of the Cahiers seem to be available at http://www.numdam.org/numdam-bin/feuilleter?j=CTGDC, what about the Supplements, containing the collected work of Charles Ehresmann, published around 1982? Best wishes, Keith
