           "Charles Francis Haanel (May 22, 1866 – November 27, 1949)[1][2] was an American author, philosopher and a businessman.[3] He is best known for his contributions to the New Thought movement through his book The Master Key System.
            In 1919, Napoleon Hill wrote Haanel a letter thanking him for The Master Key System.[10] In the letter Hill stated, "My present success and the success which has followed my work as President of the Napoleon Hill Institute is due largely to the principles laid down in The Master-Key System." - Wikipedia

The New Psychology came out in parts as separate volumes. Volume encompasses at least parts of some of those separate volumes. This appears to be a first printing as such.
