Yesterday and Today, Kuzguncuk is about the Jewish community in one of Istanbul's oldest Jewish settlements on the Asian side of the Bosporus. Written in Judeo-Spanish, an endangered language that survived for five centuries in the Ottoman lands, and translated to English, the purpose of the book is to document memories of this endangered language. The summary of historical events, told alongside childhood memoirs set in the second half of the 20th century, were meant to recreate life in a Jewish neighborhood where the Judeo-Spanish language was still alive.
