The Will to Power is a book of notes drawn from the literary remains of the philosopher Friedrich Nietzsche by his sister Elisabeth Förster-Nietzsche and Peter Gast. The title derived from a work that Nietzsche himself had considered writing. The work was first translated into English by Anthony M. Ludovici in 1910, and it has since seen several other translations and publications.

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.
