Members of The Augustan Society, Inc., are assigned a unique Membership Number. It is not clear what purpose this serves.
Membership numbers are logged in the [[Master RosterMembership Book]] to avoid duplication.
Numbers are in two parts, a letter and several digits. The letter is first letter of the surname. While usually obvious, prefixes such as de or von, and titles such as Füerst or Prinz are not counted. The prefix Van usually has been counted; it's not clear what the logic is here.
