ENThe study into stereoscopic photography in Lithuania was conducted using two mutually complementary methods. Historical facts were researched from the published and archival sources, while information on production from the publishers was substantiated by extant stereoscopic images accessible to the author. This historical research was compiled by the author in an album (Junevičius, 2019) featuring around 200 photographs from collections held by institutions in Lithuania, Poland, France and Russia alongside private collections in Lithuania. The author’s estimation is that the book includes 60 per cent of stereoscopic images produced in Lithuania prior to 1915. The data on the activities by the Russian and German publishers of stereoscopic images in Lithuania may contribute to broader research into the history of stereoscopic photography and encompass several countries.
