Yale University Library public name/title card catalog, circa 1860-1979. The cards are primarily in English, however many other languages are also represented. The entire catalog measures 4453.5 linear feet, in 8907 boxes.

The heading on the first and last card in the first of the 500 boxes is recorded in 245 subfield "p."

Each box has a separate item record, which displays the box's number (where it falls in the catalog sequence), and the main entry information from its first card.
