This collection contains digital file images of color photographs taken (mostly) by Dr. Margolis between 1954-1956 in and around Fort Defiance, Arizona and in other locations in northern Arizona and northern New Mexico. The original photographic prints are not held in this collection; the PowerPoint is the source record from which digital file images are collected. Individual image files (JPEG format) were extracted from the PowerPoint and converted into TIFF-formatted files which are available upon request. To facilitate previewing, black and white PDF print surrogates are also included. Several publications highlighting the work of Dr. Margolis have also been included. Formerly collection number HT 0023.
