The CAS USB card puts a complete Canadian air-mail research library in your pocket. On a single wallet-sized stick you get both editions of The Air Mails of Canada and Newfoundland* — the 1997 first edition (AMCN1) and the 2022 second edition (AMCN2) — plus the AMCN2 Supplement, a working update layer that adds newly discovered covers, revised census counts, corrections, reclassifications, and verifications for AMCN2 listings, keyed by cover number and linked back to the underlying research.

Alongside it is the complete run of The Canadian Aerophilatelist, Issues 1 to 146 (1985 through March 2026), and the current master index to all 146 quarterly journals. Every file is a searchable PDF, so you can look up an AMCN cover number, jump to the supplement update, and then read the TCAP article that documents it — all in seconds, at home, at a show, in the auction room, or in the exhibit hall.

To celebrate Canadian aerophilately and welcome new collectors into the field, the CAS is now offering the USB to everyone at just CAD $20 + $5 postage and handling, worldwide — the same price previously reserved for CAS members who already owned the printed catalogue.
