Memorial books can be traced far back into Jewish history. The tradition of commemorating the destruction of Jewish communities in writing dates back to the 14th century. The Shoah saw hundreds more published, beginning in 1943. They are also known as Memorbücher or, from the Yiddish word for memory, yizker-bikher. (Marie Schumacher-Brunhes, Lille)
