Included are recordings of people who survived the Soviet labor camps, and personal recollections of politicians like Stefan Korboński and Jerzy (Jur) Lerski. There are about 3,000 press clippings and articles, from "Na Straży" ("On Guard") published in Jerusalem when Polish troops were stationed in Palestine and "Polak w Libanie" ("The Pole in Lebanon", published in Beirut) to press releases from the Solidarity movement. The stamp collection contains postcards and stamps from as far back as 1818, and includes 700 postcards in a section under the heading "The Legions and their Founder".
