This series consists of correspondence between Dr. Hoffer and other physicians around the world. This correspondence, both incoming and outgoing, is arranged alphabetically by correspondent's surname, in three sub-series.

"A-1" correspondence is with physicians who have illness within their own families. Most often these physicians are seeking Dr. Hoffer's advice or assistance in treating their afflicted relatives, usually schizophrenics.

"A-2 correspondence is with physicians using orthomolecular medicine or psychiatry. These physicians are frequently requesting technical advice and detailed information concerning orthomolecular treatment.

"A-3" correspondence is with physicians who are merely requesting information regarding orthomolecular medicine or psychiatry. These requests are usually simpler than in A-2, often asking for specific information such as reprints, addresses, treatment manuals, and the like.
