Batter Up: Classifying Pre-World War II Baseball Cards Using Dewey Decimal

摘要

Within cataloging non-book items, literature on sports cards is limited and not rooted in academic research. Sports cards provide valuable statistical information and evidence of lineups. This article addresses the gap by examining Jefferson Burdick's The American Card Catalog. Known as the Dewey Decimal system of trading cards, the Catalog is the preeminent resource for collecting pre-World War II cards. This article expands upon Burdick's work and guides librarians through the building of a class number for individual sports cards. The result incorporates classification methods to support user search, and highlights the historical value of cards within library collections.
