Stiftelsen Skjulte Skatters Forlag (SSSF)/Hidden Treasures Foundation Publishers (HTFP) was established by
Johan Oscar Smith
when he started the paper
Skjulte Skatter (Hidden Treasures) together
 with his brother, the dentist
Aksel Smith on 1 January 1912.

Literature and intellectual works from SSSF have, since 1912, mainly been written and composed by members of Brunstad Christian Church (BCC). See songtreasures.org"
