A collection of the New York Public Library's Dorot Jewish Division, the Yizkor Book Collection contains more than 1,000 digitized yizkor or memorial books that document the history of Jewish communities destroyed in the Holocaust. A phenomenon for the most part of the late 1950s, the 1960s, and the early 1970s, the yizkor books evoked by the Holocaust were edited, privately printed, and distributed (often free of charge) by committees of survivors of many hundreds of the former Jewish population centers of eastern Europe. Most yizkor books are in Hebrew and/or Yiddish with a brief English-language summary sometimes appearing at the end; in a few cases, there may be substantial content in English, Hungarian, or other languages. The books tend to be long (frequently running to 600-900 pages), unindexed, and extensively illustrated with photographs. The yizkor book holdings of the Dorot Jewish Division are the most extensive in the United States, which users can search by title, date of creation, or date of digitization.
