Abstract: A wall mounted telephone index including a housing arranged to be mounted in a substantially vertical position on a wall, the housing having a front opening for access to the interior in which a stack of pivotally mounted index cards are disposed with a pivotally mounted door on the housing for closing the front opening and maintaining the cards in a storage position. A slide selector is mounted on the housing for movement into a selected position for retaining engagement with a selected card so that when the door is pivoted downward manually, the index cards overlying the selected card pivot downwardly to display the selected index card.
