The bulk of the material in this collection pertains to the years Bazzoni spent at the University of Pennsylvania (BA 1911, PhD 1914). There are three notebooks filled with student lecture notes from the years 1913-1914. Also, a collection of articles Bazzoni wrote while teaching at Pennsylvania, including several memos to the Educational Survey Committee. There is a notebook tracking his experiments while in London at King's College, and copies of two dissertations by students, presumably from the years Bazzoni was at Pennsylvania. Materials from the post-Pennsylvania years is limited to a notebook of Potential Center Displacement of Logger Tests.

These classroom notes, taken by an unidentified student, present the state of knowledge in natural philosophy, especially astronomy, during these years. There are mentions of many contemporary scientists, and much on Newton and Newtonian philosophy.
