This subseries includes three sketchbooks, two of which are annotated. 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. Despite this fact, this collection contains only three sketchbooks. The 1951 sketchbook consists primarily of ink figure drawings, but also includes notes for her WNYC Radio Arts Festival Interview, a transcript of which can be found with the biographical materials. The 1967 sketchbook includes diary entries amongst the abstract and figurative drawings. Finally, the 1969 sketchbook is labeled "Turkey" and includes felt tip marker landscape and abstract drawings.
