The three boxes in this series contain smaller boxes and envelopes of slides, most unidentified but appear to be images used in Dr. Arbib's classes and presentations. Those that were labeled in any way were transcribed into the finding aid as they were. The slides are loose (not in slide pages) but may be viewed on a light box. (Slides and overhead transparencies that were included in folders within subject files were left with those files and not separated out.)
