Dear all, I am looking for the paper J. Gray, Universal algebra in a Cartesian closed category; E.T.H. Zürich (1975) If someone has a copy of that paper and could send it to me, or could help me with locating it, that would be greatly appreciated. Thank you very much. With kind regards, Filip [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
