Card-pocket. (Reduced; actual size, 7 x 13-1/2 cm.)
To every borrower the library issues a borrower's card. 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.
Book card. (Reduced; actual size 12-1/2 x 7-1/2 cm.)
The borrower's card he places in the book pocket, the book-card he retains as a record of the loan, and the borrower takes the book away. The book-card, with all others representing the books issued on the same day, he places in a tray behind a card bearing the date of the day of issue. All the book-cards representing books issued on a certain day are arranged in the order of their call-numbers.
Tray for book-cards.
[Under this system the borrower can tell, by looking at his card, on what date the book he has was taken from the library.] If he wishes to renew it without taking it back to the library, he can do so by a letter stating that he took on a certain day a book bearing a certain number, and wishes it renewed.
