I was only introduced to philately in my 30’s and if it hadn’t been for catalogues I would have been lost. I learned a lot from my stamp catalogue. Here is a short list of why they are so necessary. I’ll be concentrating on catalogues for Canada stamps, such as the Unitrade Specialized Catalogue of Canadian Stamps.
