The collection covers Bartlett's scientific and professional work. It comprises notebooks, a small amount of correspondence, and drafts and notes for lectures, addresses and papers; many are written on the back of undergraduates' essays or examination scripts, and very few are dated.

There is no biographical material as such, but B.86 contains an autobiographical account of Bartlett's early life and time in Cambridge up to World War I. A. Notebooks, A.1 - A.42, c. 1906-1930 B.
