Publisher's Synopsis
Excerpt from The Card Catalogue: A Practical Manual for Public and Private Libraries; Including Other Uses of Cards in Libraries
The Staderini card is similar in almost every respect save that it is secured in the drawer by a sliding block geared with a ratchet. Another method of securing the cards in the drawer was invented at Breslau by Dr. Carl Dziatzko in 1879. The feature of this is a broad brass bar passing over the top of the cards. Two British methods of this period must be noted. One was devised by Mr. Dunlop, of the National Library of Ireland. It consisted of an elongated slot down the centre of the cards, through the top of which the rod was passed. As an aid in consulting the catalogue, it was possible to lift the card above the others as far as the rod permitted - in other words, until the bottom end of the slot camein contact with the rod. The other method, devised by Mr. Peter Cow ell of Liverpool in 1879, did away with the ordinary locking rod. Instead, two fixed wires passing through holes at the bottom corners of the cards were substituted. By means of slits cut from the holes to the sides of the cards, it was possible to remove or replace the cards without any trouble. More recent methods of securing cards In drawers and trays are described later. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
