This photo shows the San Mateo County Free Library library card system used from the mid-1940s through the mid-1950s. The information on the card holder reads: This book may be kept 14 days. A fine of 2 cents per day will be charged on books kept overtime. No books will be issued to persons in arrears for fines. Careful usage of books is expected, and any soiling, injury or loss, must be paid for by borrower.
