[78-L] David Whatmough's Canadian Discographies

[agp]

Over at Piers Hemmingsen's Capitol 6000 website 
(http://www.capitol6000.com) he has an interview with collector/ 
discographer David Whatmough. Its audio only (no written transcript), 
and I haven't listened to it, but he makes mention of Whatmough's 
book "50 Year Directory of Canadian 45 RPM and 78 RPM Records 1940 to 1990".

Can anyone give me some background on this book and how to acquire it 
as Hemmingsen doesn't seem to have that info at Capitol 6000
