Charles Ammi Cutter (1837-1903), the author of what is in Mr. Ranz’s opinion the finest library catalogue ever made. Cutter’s masterpiece is the five-volume catalogue of the Boston Atheneum, published between 1874 and 1882. “I’m not sure he wasn’t the greatest cataloguer that lived,” Mr. Ranz told me. The work is three thousand four hundred and two pages long, and is elaborately and commonsensically cross-referenced; it cost the Athenaeum almost a hundred thousand dollars to produce. It is still of interest and utility to historians—as is the card catalogue for the Athenaeum, which Cutter also developed.
