What is the proper format to use for initials at the bottom of the letter when there is no dictator of the letter, but only a typist? Example:
JWM/ds indicates JWM was dictator and ds was typist.
ds indicates there was no dictator and that ds was the typist.
Is DMS/dms proper when there is no dictator and dms is the typist?
DMS/ds indicates that DMS composed the letter, and ds typed it. However, not everyone includes the initials of the person who composed the letter, as that information is apparent from the signature. It is quite common to find just the typist's initials (/ds) on business correspondence.
