This card is made of heavy, colored tag-board, and contains the borrowers' name and address, and his number in the series of borrowers' numbers. The librarian, before delivering a book to a borrower, takes from the pocket the book-card, writes on it the number found at the top of the borrower's card, and after it, with a dater, stamps the day of the month. At the same time he stamps the same date on the borrower's card, and on the pocket in the book or on a dating slip pasted in the book opposite the pocket. [Illustration: Book card.
