Abstract
Abstract Relatively inexpensive slide storage trays are provided for use with a single slide projection tray. The slide storage tray has alignment and indexing means cooperable with the projection tray so that the trays can be temporarily mated for transfer of slides from the slide compartments of one tray to the slide compartments of the other tray while maintaining a predetermined arrangement or sequence of slides relative to the compartments. A pusher device may be utilized to facilitate transfer of slides from certain types of projection trays.
