This collection consists of field notebooks, drafts of speeches or articles, and reference material created and collected by C.D. Bunker, an assistant curator at the University of Kansas' Natural History Museum in the first half of the 20th century.

This collection includes Stan Roth's field survey notes, annotated topographical and highway maps of Kansas, and records related to trips to Florida and Hawaii that Roth took annually with advanced high school biology students while teaching at Lawrence High School in Kansas from the 1960s through the 1990s.
