The Spirits' Book (Le Livre des Esprits in original French) is one of The Five Fundamental Works of Spiritism, and was published by the French educator Allan Kardec in 1857 April 18. It was the first and remains the most important spiritist book, because it touches in first hand all questions developed subsequently by Allan Kardec.

The Medium's Book was the second book of the Codification of the Spiritist Doctrine, first published in 1861. Composed of 32 chapters, the book is divided into 2 main parts.

The first is an overview of Spiritism, and a discussion of the many theories used against spiritism and their many inconsistancies. The second part is a detailed classification of paranormal phenomena, with a focus on those capable of communicating messages, and thorough descriptions of the mechanisms that are involved. 

Heaven and Hell (Le Ciel et l'Enfer in the original French) is a book published in 1865 by Allan Kardec, the fourth tome of the fundamental works of Spiritism. Its name was intentionally taken from a previous book by Swedenborg, it was also subtitled "Divine Justice According to Spiritism". It is divided into two parts named "The Doctrine" and "The Examples".

The Genesis, Miracles and Premonition According to Spiritism (La Genése, les Miracles et les Preditions selon le Spiritisme in the original French) was the last book published (1868) by Allan Kardec, just before his death. It tries reconciles science and religion and develops a series of important scientific and philosophical topics, relating them to Spiritism.
