I believe that Logan Kleinwachs should be congratulated for the tremendous effort by making this directory available to us. Though smaller than the 1929 Polish Business Directory it enables an interesting comparison of the businesses in every location in amatter of 3 years. I myself research the KOENIGSBUCH family >from Brzesko (image 209 in the Directory) and managed to locate Koenigsbuchs in the 1926 version who were not there anymore in 1929 and vice versa. Now I have the questions which will lead me hopefully to some answers. Jacob Rosen Jerusalem
