These are the key writings of the Unity Church, a major New Thought movement. Most of the early writings of Charles Fillmore, the founder of Unity, are in the public domain in the US because they were not renewed in a timely fashion. The two books below published prior to 1923 are in the public domain in the US because of their date of publication. A search of the online copies of US copyright office records for this period showed no renewals for the rest of these works.
