Amoeba studies

The research papers consist of three types of material based on size (and format): 1) research files; 2) index card files; 3) oversize graphs, charts, and diagrams. There are approximately 3 boxes of research files that contain various data on microfungi and cellular slime molds. These consist of genus/species isolations and determinations, experiment records and notebooks, dichotomous keys, notes on photomicrographs, laboratory procedures and media, and related records.

Most material relates to Dr. Raper's research on Dictyosteliaceae at the University of Wisconsin and on Penicillium at NRRL. There are 5 boxes of index cards that consist of indices for The Genus Aspergillus (1965) and The Dictyostelids (1984), as well as author and subject indices. One box contains oversize graphs on antibiotic production and diagrams of D. discoideum. The photographic record of Dr. Raper's research is integral to these records and is contained in Series 13: Photographic Material.
