Sargent Student Studying, ca. 1930s (Books)

An enlargement of the bookshelf on the college student's desk revealed the following titles: Textbook of Anatomy and Physiology, 9th ed., College Zoology, by Heg[ner], and Organic Chemistry.

I was able to identify the first book as the ninth edition of Textbook of Anatomy and Physiology, by Diana Clifford Kimber, Carolyn Elizabeth Gray, and Caroline E Stackpole, which was published by Macmillan in 1934.

The second book, College Zoology, was authored by Robert W. Hegner and was also published by Macmillan, with a third edition in 1932 and a fourth in 1936.

Although I didn't attempt to track down details about Organic Chemistry, the presence of the other two books confirms that this photo dates to 1934 or later.
