The APA Archival Photo Collection was established in 2002 with an anonymous donation of 36 photo portraits and sketches used as figures in Hilgard’s American Psychology in Historical Perspective. The identity of the photographers and the sketch artists are not known. Another publication Street’s American Psychological Association 1992 Centennial Calendar became the second series of the collections. Gradually new groups of photographs were ... donated... and became the core of the Legacy Photo Series, with over 1000 items. Monitor on Psychology, the official publication of the APA, donates many photographs used as illustrative material in their articles. Currently there are over 2,300 photographs and 1,500 in digital format, many in high resolution, ready for publishing.

Another source of information about photographs is Psychological Images in Publication, many of which can be found in the APA Library holdings.
