Hi...I am Bohemian (now called Czech) and was doing a search for family history and found this website; which can direct you to others. Try this:
www.jarelative.com/czech/ Where it shows czech you can type in slovak for other cookbooks: www.jarelative.com/books/(type in this space slovak or czech or hungarian or ukrainian, etc.) The photos that are put on this website (from Poland, or Czechoslovakia, etc) are beautiful, under Photo of the Week, which changes every Monday. Hope you can find the cookbook that was mentioned. Good Luck!
