For starters, The Ukraine Archival Records held by the Province of Alberta. It has a whole file on Chomiak, including his own details about his days editing the newspaper Krakivski Visti. Chomiak noted he edited the paper first in Crakow (Cracow), Poland and then in Vienna. The reason he edited the paper in Vienna was because he had to flee with his Nazis colleagues as the Russians advanced into Poland. (The Russians tended to execute collaborators well as SS members).
