ABSTRACT OF DISCLOSURE The invention refers to a card index, preferably a telephone subscriber's index, including a flat casing having a top, side walls and a front opening, a tray adapted to be pushed into and pulled out of this casing through said opening, and a pile of index cards supported on the tray and intended to have information, such as telephone numbers, accounts etc., written down thereon. The index is furthermore provided with manually operable means in the form of depressible keys with dogs provided on the underside of the keys for determining, before pulling out the tray, which index card is to be presented to an operator by depression of an optionally selected one of said keys so as to cause the dog thereof to bend down the front portion of a number of said index cards and thereby at the same time to urge the remaining cards lying thereabove into engagement with the inside of the top of the casing, where they are retained in position, when the tray is pulled out together with the bent-down cards, by depending catch members on the casing top at the front end thereof. An upright bar is provided on the tray in front of the front edges of the index cards to bring the bent-down cards back together with the tray when pushing in the latter into the casing.
