The Henry Borsook Papers cover the years 1958 to 1983, but significant gaps are present. Section 1 is incoming and outgoing correspondence primarily covering the years 1960 to 1965. It illustrates several facets of Borsook's career, including his relationships with colleagues, graduate students, and the food and vitamin industry, most notably with the American Institute of Baking and Miles Laboratories. Section 2 provides manuscripts and notes, including notes for talks given in the 1970s on food and international development. It shows the breadth of Borsook's interests and contains his book reviews and writings on medical history and on art history. Section 3 contains papers from the late 1970s and early 1980s related to the Meals for Millions Foundation. At the end of the collection is a small amount of biographical material, some reprints, slides, and several books on food and nutrition with annotations made by Borsook.
