"In The Middle Of The Road" is a book written by Gaon that includes poems, family stories and photos. He edited "Spices from Spain", a collection of Ladino quotes (with Hebrew translations) passed down to him by his father, a well-known historian. He also published a second edition of "Eastern Jews in Israel," an encyclopedic work originally published by his father. The complete work includes biographical information on almost 3000 rabbis, scholars and others in Spain, France, Italy, the Ottoman Empire including the Balkans, and the Middle East and North Africa who visited or immigrated to Israel, sometimes moving there to ensure they could die in the Holy Land. Gaon wrote an autobiography in Hebrew named O'd Ani Pose'ah-Sipur Hayai, published in 2017 by Yedioth Ahronoth.
