This is a complete catalogue of all the members of the Society since 1838. It lists the birth and death dates, year of election and section affiliation of members, as well as the names of those who have given eulogies and the name or site of the publication. Some items of information are uncertain. Sweden-Finland switched to the Gregorian calendar in 1753, while Russia stuck to the Julian calendar until 1918. This has made it difficult to determine the exact dates of birth and death during the period of autonomy because normally reliable sources offer conflicting information. Similarly, the information on people who have served during the period of independence poses a number of problems. In certain cases, the National Biography of Finland, Uppslagsverket Finland, Encyclopedia Britannica, Nationalencyklopedin and the archives of the Finnish Society of Sciences and Letters contain conflicting information. Birth and death dates engraved on tombstones and given in obituaries have been assumed to be correct.

The Society initially had regular members and honorary members. In 1922, a third category of membership was introduced: foreign members. Before 1922, a foreign citizen could only be elected to the Society as an honorary member. This explains the high number of honorary members up until 1922. From 2021 onwards, a person permanently residing in Finland can be elected as a regular member regardless of nationality.
