Information was gathered from licensing bureaus, medical schools, AMA Membership records, and medical societies, in reference to the physician. No family or detailed health information is available. A few cards were created for Canadian and international physicians based on their obituaries. Licensing cards show the state and year of licensing, based on the name given when examined, and were submitted by each state's medical examiner boards. Graduation cards show only the school the doctor was attending at the time of graduation.
Physician cards have the most information.
Earlier cards include information about early education, childhood locations, and include licensing information. In a few cases thumbnail pictures or obituaries are attached to the cards. The index includes physicians who died after 1905. It is useful in identifying cards that may have gone missing or disintegrated over time. Before 1907 This contains abstracts of information from various obituary sources with the appropriate references.
