The Lost Secrets of the Jedi was a bestselling book during the New Republic era. It purported to be authentic and claimed to deal with the "secret masters" of the galaxy; implying the Jedi Order. The Galactic Archives on Atzerri added it to its catalog list.

During his visit to Atzerri in 16 ABY, Jedi Master Luke Skywalker bought the book at a satellite outlet in the Trader's Plaza while under the pseudonym Li Stonn; hoping to discover the whereabouts of his mother. He went to read the book at a nearby club bar called Jabba's Throne Room. The book was presumably a fraud along with the Archive's other publications including Principles of Power and the Sith book of offerings and rituals.
