The first video is about National Archives of Georgia (which is under the Ministry of Justice) providing documents for the researches from Amsab - Institute of Social History. The documents were used for preparing a paper entitled “Camille Huysmans op missie in Georgië” (Camille Huysmans on a mission in Georgia? http://www.amsab.be/index.php?option=com_content&task=view&id=909&Itemid=29 ) about a visit of Camille Huysmans (then leader of the 2nd International, later prime-minister of Belgium) to Georgia in 1920(?).

Disclaimer: I don't speak Georgian  Concerning the third video, see http://www.justice.gov.ge/index.php?lang_id=ENG&sec_id=23&info_id=3571  The fourth video seems to be on the same topic as the third one. Note that the audio is in Russian.
