David Murphy has written a review of CTCS in the journal Formal Aspects of Computing, Vol. 3, No.2, in which he says, in part, ``Category Theory for Computer [sic] Science was written in TeX and is available by ftp''. Leaving aside that he got the name of the book wrong, the whole book is not available by ftp. The publisher owns the copyright and probably would take a dim view of that. What is available (but only since about 36 hours ago) is a file of updates. It is available by anonymous ftp from triples.math.mcgill.ca (Internet: 132.206.150.30) under the name pub/barr/ctcsupdate.tex. ====================================
