[2] Aside from indicating the range of his thought and originality of his mind,[9] the book has historical value because it describes the scope of Tesla's early inventions.

[10] Tesla was unconcerned with the financial aspect of the book but though in the future it would make a good amount of money.

[11] Edwin Armstrong, the inventor of FM radio, commented on the importance of the book and stated in the middle of the 20th century: Who today can read a copy of The Inventions, Researches and Writings of Nikola Tesla, published before the turn-of-the-century, without being fascinated by the beauty of the experiments described and struck with admiration for Tesla's extraordinary insight into the nature of the phenomena with which he was dealing?

But one can imagine the inspirational effect of the book forty years ago on a boy about to decide to study the electrical art.

[12] Margaret Cheney, in Tesla: Man Out of Time, used the text of the book to call attention to the fact that Tesla indicated that one of the uses of the experimental equipment would be for the professional field of "harmonic and synchronous telegraphy" and that "vast possibilities are again opened up" for the radio arts of the time.
