The Clark & Beuttler records span 40.5 linear feet and date from 1920 to 1968. The collection contains notes, clippings, small sketches, and correspondence, all organized by project. The collection also consists of black-and-white photographs, negatives, and Clarke’s postcard collection which is organized by location and/or subject.

Flat files contain architectural drawings and reprographic copies of work, primarily residential, done by Clark & Beuttler between the mid to late 1950s and into the 1960s, architectural awards and certificates, and Clark’s student work, the majority of which are watercolor paintings of buildings and date from the early 1920s.
