Reports and articles by the Ghetto Archives staff: "Encyclopedia of the Ghetto" by Oskar Rosenfeld, 01 December 1943-08 March 1944 The author explains why such an encyclopedia is necessary: New words and expressions have been created in the ghetto which will not be understood in the future, and expressions have changed their meaning due to the circumstances. It is therefore necessary to explain these words, so that researchers in the future will know what thewords meant. Additionally, brief biographies of central figures in the life of the ghetto have been compiled.
