Library of Congress Punch Card

Description:

The late 1960s and early 1970s were a time of rapid change in processes for cataloging and circulating books at the U.S. Library of Congress. Computers were introduced for preparing cataloging records for libraries across the nation, and for tracking and distributing books sent out on interlibrary loan.This is one card used in the process. It relates to a volume entitled Western Electric Co Info Care 1A Audiometer that had call number RF151 W21. It was checked out on 12-12-72 to borrower OS500. A mark on the bottom edge of the card reads: HP/ECC-1294-0.
