Responsa of the esteemed Gaon Rabbi Shlomo Kluger ,   Av Beit Din of Brody, 1863, to the esteemed Rabbi Eliyahu of Marder from Dzikev, likely the publisher of ”Chiddushei HaRan” and other books, who was then relatively young. At the beginning of the letter, he apologizes for not having the leisure to reply in detail: ”...But since it concerns my books, I am compelled to reply, albeit briefly...” Apparently, the letter, which deals with chametz-related matters, was written regarding his book ”Ma'aseh Yedei Yotzer” on the Haggadah of Passover, which was printed in the same year. The letter, apparently, was not printed!
