Early issues printed lectures delivered at meetings of the society along with an annual report of the society's activities. Articles other than those read at meetings began to appear in the mid-1930s, along with book reviews. Early articles focused on the history of Siam and exploration of its provinces. Obituaries of prominent members became a regular feature following the obituary of Prince
Damrong Rajanubhab in 1944. The size of the journal shrank in the 1940s, then expanded from the mid-1950s with more articles on archeology, anthropology (especially of hill people), and other social sciences.
Before World War II Prince
Damrong Rajanubhab authored 10 articles between from the first issue in 1904 and 1939. Prince
Dhani Nivat authored 17 articles between 1930 and 1965.
George Cœdès authored 11 articles between 1918 and 1944. Other prolific contributors in the early years included Jean Burnay and
Robert Lingat.
King Vajiravudh In 1912, the journal carried an article by King
Vajiravudh, Rama VI, on “The Romanisation of Siamese Words.” For some years, the society had discussed the need for a standard system for transcribing Thai into Roman characters. A member, P. Petithuguenin, had proposed a system. In his article, King Vajiravudh proposed an alternative system, which had an “Orientalist” method for transcribing consonants in words derived from Pali-Sanskrit, a parallel and different system for transcribing consonants in “purely Siamese” words, and 30 representations of vowel sounds. The king concluded: “I should be glad to see some sort of uniform system adopted, rather than to have to endure the haphazard and fanciful systems, which not only each body of men but also each individual, seems to use for romanising my language.”
After World War II In the post-World War II period, Hans Penth authored 24 articles between 1967 and 2003, though many were short notes. The largest contributors were Michael Smithies, 22 articles between 1971 and 2002,
Phraya Anuman Rajadhon, 19 articles between 1951 and 1967, and
Michael Vickery, 13 articles between 1973 and 1995, including his translation of the only chronicle text discovered in the 20th century. The largest span was achieved by
Barend Jan Terwiel who authored 11 articles over 47 years from 1972 to 2019.
Epigraphic and Historical Studies series Between Vol 56/2 (July 1968) and Vol. 67/2 (July 1979), JSS published 26 articles co-authored by
A. B. Griswold and
Prasert na Nagara. Of these, 24 were in a series of “Epigraphic and Historical Studies,” which provided the first English translations and interpretations of the corpus of inscriptions, mainly from Sukhothai and associated sites. The series was subsequently published by the Historical Society of Thailand. Griswold (1906–1991) was a Baltimore native, Princeton graduate, and investment banker who was parachuted into Thailand behind Japanese lines during World War II. Prasert na Nagara (1918–2018) began his career as an agricultural engineer before discovering his talent and love for languages and history. During the creation of the series, he would spend one month a year working with Griswold at his US home. ==References==
