The CRHA has been around since the 1930's and has produced a wonderfully useful magazine for well over 50 years. The CRHA has digitized the archives of these publications and has them available on line, for free !
The addy:

There is a google search link I haven't yet tried but I am appreciative to have this valuable resource for research availbale on line.
