- Summary:
- The History of Disabilities program provides access to primary sources written using terminology that was in common use by the medical establishment and general society at the time, and describes diagnoses, methodologies, procedures, and treatments that may no longer be used or were debunked by later research. Users may come across words and expressions describing individuals and groups that they find condescending, upsetting, disconcerting, offensive, and not acceptable today. MiFhGG
