Archives of the History of American Psychology

Established in 1965, the Archives of the History of American Psychology is the world’s largest repository of manuscripts, monographs, media, and artifacts relevant to the history of psychology and related human sciences.

The collections document the history of psychology in all of its forms, tracing it from the laboratory rooms in the late nineteenth century to the hospitals, schools, and businesses throughout the twentieth century.

The CHP is dedicated to preserving, organizing, and documenting these materials and making them available for research, scholarship, and interpretation.
