Left to right: A drawer from Olin Library’s union catalog; Catalog Cards; Olin Library Card Catalog, 1961.
Cards for any given item were filed in multiple locations: under its title, author’s name, Library of Congress Subject Headings, and – where applicable – variant titles and names. The card catalog cases were removed and the remaining cards recycled in 2007.
Three varieties of card format found in the Olin union catalog: Handwritten cards in “library script,” used in the 19th and early 20th centuries; Manually typed cards; Printed cards generated from machines.
The Olin card catalog (as it appeared in the early 1960s) occupied half of Olin’s first floor public spaces.
