In late 1975, Zlotowitz wrote an English translation and commentary on the Book of Esther in memory of a friend, and asked Scherman to write the introduction. The book sold out its first edition of 20,000 copies within two months. With the encouragement of Rabbi Moses Feinstein, Rabbi Yaakov Kamenetsky, and other Gedolei Yisrael, the two continued producing commentaries, beginning with a translation and commentary on the rest of the Five Megillot (Song of Songs, Ecclesiastes, Lamentations and Ruth), and went on to publish translations and commentaries on the Torah, Prophets, Talmud, Passover Haggadah, siddurs and machzors. By 1990, ArtScroll had produced more than 700 books, including novels, history books, children's books and secular textbooks, and became one of the largest publishers of Jewish books in the United States.
