Series consists of bound notebooks and catalogues, some in loose leaf form. Some notebooks are handwritten; most have been transcribed. The catalogues list in columns the flora and fauna observed on specific dates and locations. Soper illustrated some of the notebooks with colour pencil sketches and occaissionally pasted in a photograph. The notebooks are in roughly chronological order and document both his private naturalist studies and his professional work for the federal government and the University of Alberta. These books are the raw data of his work as a naturalist researcher in the Candian Arctic and Prairies.
The series title is based on the contents of the records.
