The collection consists of artefacts donated to the Museum of the Occupation of Latvia by Paulis Kļaviņš in 2006, and by Ģederts Melngailis on several occasions, beginning in 1994. Most of the artefacts in the collection are materials donated by Kļaviņš in 2006: brochures, wrappings used in demonstrations and other actions, badges, etc. Melngailis' donation consists mainly of copies of KGB reports on the activities of the 'Action of Light'.
