They are found at ftp.math.mcgill.ca/pub/barr/pdffiles{Index.html,Subjindx.html}. There is also a new paper there, On *-autonomous categories of topological modules, whose abstract follows: Let R be a commutative ring whose complete ring of quotients is R-injective. We show that the category of topological R-modules contains a full subcategory that is *-autonomous using R itself as dualizing object. In order to do this, we develop a new variation on the category chu(D.R), where D is the category of discrete R-modules: the high wide subcategory, which we show equivalent to the category of reflexive topological modules.
