The Editors are in the process of preparing a number of TAC Reprints that will consist of a number of papers by Peter Freyd that were circulated but never published. The papers will be individually refereed and when ready this number will appear. In the meantime, as papers are approved they will be posted temporarily at ftp.math.mcgill.ca/pub/barr/abcat/ The first such paper has now been posted under the name homotopy.pdf. It is the one that shows that the homotopy category is not concrete. best wishes, Bob Rosebrugh =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Robert Rosebrugh, Managing Editor http://www.tac.mta.ca/tac Theory and Applications of Categories tac@mta.ca Dept of Math, Mt.
