An automatic slide feeder according to one embodiment of the present invention may comprise a housing configured to define an input slide tray, an output slide tray and a scan slide tray. A slide actuator operatively associated with the housing moves a slide from the input slide tray to the scan slide tray. A control system operatively associated with the slide actuator and a document scanner operates the document scanner to scan a slide positioned in the scan slide tray and operates the slide actuator to move a new slide from the input slide tray to the scan slide tray after the slide positioned in the scan slide tray has been scanned.
