The National Archives of Thailand is moving ahead with the digitization of documents, photos, maps and microfilms, some dating back over a century as well as enabling online searches.
There are two kinds of archive materials — written materials and audiovisual records. Audiovisual records include photos, films, videos, slides, maps, plans and more. Only archive documents dated over 25 years are accessible to the public.
