According to biographical accounts, Betty Parsons was an avid sketcher, having acquired the habit dating from her studies with the English artist Arthur Lindsay in the 1930s. This subseries includes thirty-two of her sketchbooks of varying sizes, many of which are annotated with diary entries and other notes, such as 1951 notes for her WNYC Radio Arts Festival Interview, a transcript of which can be found in 7.2: Biographical Materials. The sketchbooks contain abstract, landscape, and figurative drawings and paintings in ink, felt tip marker, gouache, pencil, and other media.

Also found are two notebooks containing dress patterns by Parsons.
