Notes:

It should be noted that the UCLA Library displayed much of Dr. Klemin's papers and research from December 7, 1964 to January 31, 1965 in the Department of Special Collections (Room 120 College Library building), in the Engineering & Mathematical Sciences Library (Room 8270 Engineering 11), and the University Research Library. UCLA library claims its Klemin Collection "contains more than 60,000 pieces of indexed research materials in the form of lectures, correspondence, original photographs, technical data, reports, specifications, and designs, and thus provides a rich source for the study of aeronautical development during the first half of the twentieth century."
