Abstract
<jats:p>Dmitrii Vladimirovich Filosofov (1872–1940) was a Russian intellectual, publicist, public figure, who emigrated and lived in the Polish Republic since 1920. His literary and journalistic heritage of this period is significant, it continues to attract the attention of philologists, cultural scientists, historians. Oleg Korostelev published a collection of his pre-emigration works in Russian (2010); a fragmentary publication of the epistolary heritage of the publicist continues. In 2015, P. Mitzner published two volumes of the publicist's works translated into Polish. However, a significant part of Filosofov’s works in 1920–1928s was not included in the publication: the articles on the protection of the legal status of Russian refugees, emigrants, interned anti-Soviet formations; publications-investigations of the Operput-Upelinets case, the Russian Academic group case, and many others. Filosofov was active in his social life. In Russian and Polish archives there is a significant amount of unpublished heritage of Filosofov: letters, certificates, appeals to various Polish authorities, reports on visits to internment camps, etc. The problem of their scientific publication continues to be relevant.</jats:p>
