#OED
I have a compact edition O.E.D. published in 1982. In it they list
their address as Oxford University Press Walton Street, Oxford OX26DP. If
any of the Oxford folks check out CServe, I'll add my two cents to say that
I would buy it on cd-rom for under $200 (and that's only because I love it
so much), more than that and it remains in the hands of the institutions
and the fabulously wealthy.
