Despite the relatively small size of the collection, the papers of Albert de Rochas open an important window onto the development of psychic science in fin de siecle France and onto the cultural impact of Spiritualism. The collection includes a scattered, but valuable selection of correspondence with fellow psychic researchers, editors, mediums, and other individuals interested in psychic research, and a valuable set of 69 spirit and psychic photographs, that Rochas collected as evidence of psychic forces, and as documentation of séances, mediums, and "sensitives." Rochas' work on the exteriorization of sensibility and studies of Maria Mayo (Lina), Charles Bailey, and Eusapia Paladino are relatively well documented, and his interests in the laws of psychic phenomena, reincarnation, and the exmigration of the living soul run throughout.

Other aspects of Rochas' career are much less well documented. There is little of family interest in the collection, and only a few items pertaining to his interest in ancient history or engineering. His military career is also poorly documented, although the collection includes a number of letters from former colleagues in the military, some of a personal nature and others relating to military history.
