#TIH#OTD 06 Sep 1903: Death of Charles Ammi Cutter (b. 1837), US #librarian best remembered for Cutter Expansive Classification: a system of shelving by standardized class numbers so #books on related topics sit together. He also helped produce the US’ 1st public #CardCatalogue and played a major role in making card cataloguing—versus the old practice of chronologically listing titles in ledgers—the international model. #GLAM#BookHistory#Libraries @bookhistodons
