American Card Catalog

ACC (American Card Catalog): Reference book published from 1937 to 1960 by hobby pioneer Jefferson Burdick. Burdick's system of letter prefixes and number suffixes to classify pre-WWII card sets (e.g. T-206) are still in use by The Hobby today.

Some common ACC prefixes include:

• B: Blankets and felt items
• C: Canadian tobacco cards
• E: Pre-WWI candy and caramel cards
• F: Food issues
• H: Advertising and trade cards
• M: Periodicals
• N: 19th Century tobacco cards
• R: Post-WWI candy and gum cards
• T: 20th Century tobacco cards
• V: Canadian candy and gum cards
