The Archives of the History of American Psychology (AHAP) was established in 1965 at The University of Akron to promote research in the history of psychology by collecting, cataloguing, and preserving the historical record of psychology. The central feature of the AHAP is the manuscript collection, which includes the papers of over 740 psychologists. The growth of the repository exceeded projections, both in the rate at which materials were donated and in their diversity. This expansion led in 1976 to the establishment of the Child Development Film Archives, a unit that cares for both research footage and instructional films. This expansion was followed, in 1980, by a decision to supplement the numerous unsolicited gifts of books by devoting space to the published literature dealing with the substantive content of psychology as well as with its history and philosophy. Since its inception the archives has continuously acquired apparatus, equipment, testing materials, and all forms of media.

Classics in the History of Psychology is an effort to make the full texts of a large number of historically significant public domain documents from the scholarly literature of psychology and allied disciplines available on the World Wide Web. There are now over 25 books and about 200 articles and chapters on-line. The site also contains links to over 200 relevant works posted at other sites.
