Portrait of John Cotton Dana John Cotton Dana,  A Library Primer — Chapter XXXII, Charging systems (1899)

“ When a borrower returns a book the librarian can learn, from the date on the pocket, whether or no a fine should be paid on it; if not, he can, if in haste, immediately take out the borrower's card from the book pocket, stamp the date of its return at the right of the date on which it was lent, thus canceling the charge against the borrower, and lay the book aside and look up its book-card later. ”
