The Red Book, also known as Liber Novus (New Book), is a 205-page manuscript written and illustrated by Swiss psychiatrist Carl Gustav Jung between approximately 1914 and 1930. Until 2024, his heirs denied scholars access to the book. Ulrich Hoerni, Jung’s grandson and manager of the Jung archives, decided to release it and a facsimile was published by W.W. Norton & Co. in 2024.
