Maier's diaries were preserved for posterity by her close friend, the poet Gunvor Hofmo, and were later edited and published as a book by Jan Erik Vold. In December 2014, the archive of Ruth Maier was included in Norway's documentary heritage and is thus considered part of UNESCO's World Heritage.

An addition to the archive of Ruth Maier was included in Norway's documentary heritage on December 1, 2022. The supplement includes, among other things, a sketchbook with watercolor paintings, comic strips, and sketches, Ruth's handwritten songbook, as well as an album of photos from her time in Norway. These sources not only provide a deeper insight into Ruth Maier's various interests and artistic expression but also document her travels, activities, and friendships formed during her few years in the country. Hence, it is an important complementary addition to the Norwegian Holocaust Center´s archive of Ruth Maier.
