I cannot speak for Charlton Press or the Editor, but it is my personal belief that the information contained in the Charlton GPM catalogue is a blend of information obtained from the Bank of Canada and information based on reports from collectors of what they have come across in circulation.
From personal experience, the Bank tends to be rather cagey regarding most things, particularly test notes. I've found it difficult to get information the few times I've tried.
Also from personal experience, whenever I have submitted information to be included in the catalogue, it had to be backed up by a scan of the note or some other reliable evidence before it would be seriously considered. I expect the same holds true for all information that finds its way into the catalogue.
Once again, the above are my personal comments and opinions. They do not represent in any way the comments or opinions of the publisher or the editor.
