Zusammenfassung:	A system for alerting users of standard microfiche readers to updating of stored information. Printed "update" sheets permit a user to make full notation of complete information for ready reference by subsequent users. An illuminated viewer allows placement of a coded transparent grid card beneath a fiche on the viewer illuminated panel so that frame numbers are visible through the fiche. By use of permanent or washable translucent ink or opaque ink marker pens, coordinate squares of the fiche are appropriately marked to indicate updated information or deleted information.
