HFC 190 - International Census of Small Mammals (ICSM)

The bulk of the collection documents research conducted by Dr. Calhoun during his career at NIMH. Users will also find much information in Calhoun's writings about NIH internal and external politics. Calhoun was often on the cutting-edge of behavioral research during a time of dramatic scientific organizational change at NIH. Calhoun arranged the entire corpus of his research documentation within a series entitled the Historical Flow Chart (HFC). In addition to this, Calhoun employed several other organizational schemes, such as numbered Section on Behavioral Systems (SOBS), Unit for Research of Behavioral Systems (URBS), Internal Research Query (IRQ), Research Communications (RC), "Review and Synthesis," and alphanumeric document sets. Users will find these organizational codes throughout the collection. Calhoun often duplicated documents in these sets within the HFC. Boxes 19, 135, and oversize 2 contain Calhoun's own HFC diagrams and documentation about how his research interrelated and how his papers were organized. These materials provide exceptional insight into Calhoun's own mind and thought processes.

A variety of audiovisual records supports the paper documentation. Audio reels and audiocassettes, video reels and videocassettes, and motion pictures were created from 1957 through 1988. Small sections of the collection hold some biographical information about Dr. Calhoun's life and career, along with a disparate group of NIMH administrative reports and correspondence.

Communication of research results and investigative theories are revealed in a set of reprints of Dr. Calhoun's writings (1941-1986), which are arranged by set numbers, and are followed by drafts and versions of other writings that continue beyond the dates of the reprint set or are not included in it.
