published in 1980  by
    John Wiley and Sons  NY Chichester Brisbane Toronto Singapore

Hope this helps.

Dear Alan,
my postings to Blacksheep don't seem to make it, these days  :-(
(Possibly Verizon, my ISP, is considered by Blacksheep as a spam conduit?)
Could I ask you to kindly re-post this msg. to the RSGB reflector, as
the subject may be of interest to others in the LF group?
Thanks in advance and 73
