Nostalgia for the motherland, the uncertainty of the future encouraged making earlier the beginning of the Lithuanian state, the search again for Lithuanians in all possible ancient civilizations, the publishing of counterfeit unconvincing historical documents. The main problems of this article are what symptoms of 'declining' historiography did the then Lithuanian exile historians identify and how did they propose to 'cure' them. The purpose of the article - to discuss the problems of the professional organization of the science of history and the trends of historical thought in the United States and Canada in the period of 1948-1990. Its tasks are to examine and reveal the characteristics of the creation and performance, approach to the profanation of the history of science and the manifestations of amateurism in the organizations of Lithuanian emigrant historians in the same period.
