Nachlass is a German word, used in academia to describe the collection of manuscripts, notes, correspondence, and so on left behind when a scholar dies. The word is a compound in German: nach means "after", and the verb lassen means "to leave". The plural can be either Nachlasse or Nachlässe. The word is not commonly used in English; and when it is, it is often italicized or printed in capitalized form to indicate its foreign provenance.
The Nachlass of the Austrian philosopher Rudolf Steiner is housed in the Rudolf Steiner Archiv in Dornach, Switzerland. This file drawer houses the philosopher's letters to individuals with surnames from N through Z.
