We invite submissions to these Proceedings from anyone interested; papers submitted will undergo the usual JPAA referee process, and we are hopeful that the final Proceedings will be ready before summer 1998. Topics suitable for the Proceedings include any of the subjects to which Michael Barr has contributed, such as homological algebra, triples, embeddings, exact catgeories, torsion theories, topos theory, topology, *-autonomous categories, universal algebra, logic, linear logic, computer science, or linguistics. The submission deadline for the BarrFest Proceedings is 15 September 1997. Please send five (5) (paper) copies before then to R.A.G. Seely Department of Mathematics McGill University 805 Sherbrooke St W Montreal H3A 2K6 Quebec, Canada (If possible) please send an email message to rags@math.mcgill.ca indicating the title (and authors, if other than the sender of the email) of the paper, as well as an abstract (in standard ascii format, maximum 1 page) of the paper. If you are able to provide a uuencoded, compressed PostScript file (300 dpi), please mention this in your email as well. If having the electronic file will speed up the refereeing process, we will get in touch with you to request such files. For further information, please contact Robert Seely <rags@math.mcgill.ca>.
