Hi, has anyone an electronic copy of the following paper: Rourke, C. P.; Sanderson, B. J. $\triangle $-sets. I. Homotopy theory. Quart. J. Math. Oxford Ser. (2) 22 (1971), 321--33 It seems my library has no subscription to the older issues. I would greatly appreciate obtaining a copy of it. Thanks, Jean-Pierre Marquis [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
