The Institute of War Losses, guided by its statutory mission of scientific and educational activities, establishes cooperation with museums whose scope of activity includes, among others, the history of lands formerly belonging to the Republic of Poland.

These include, for example, the Stanisław Staszic Museum in Hrubieszów and the Borderlands Museum in Lubaczów. The agreements signed with these institutions mark the beginning of further scientific, research and exhibition cooperation aimed at disseminating knowledge about the losses of identity, property and human life suffered as a result of Soviet and German aggression against Poland.
