From the Bangkok Post:
The Journal Of The Siam Society, the oldest and most prestigious academic publication in Southeast Asia, has taken a major step by making all of its contents available online.
A total of 99 volumes with more than 2,000 articles running to over 30,000 pages of scholarship can now be perused, free of charge, by ordinary members of the public.
JSS, as it is often known, first appeared in 1904 and is still going strong. The current issue and all back issues, published over a period of 108 years, can now be accessed [here].
