《卡耐基演讲与口才(英文原版)》内容为：For many years, Dale Carnegie's name hasbeen synonymous with winning friends and influencingpeople. How to Win Friends and Influence People is one of the best sellers of all time in nonfiction and has brought him international popularity. But How to Win Friends and Influence People was not the first book written by Dale Carnegie.

In 1926, Dale Carnegie wrote a book entitled Public Speaking and Influencing Men in Business. This was a textbook on public speaking, and, up to the present date, has been one of the official textbooks of the world-famous Dale Carnegie Course in Effective Speaking and Human Relations. It has also served as a textbook for Y. M. C. A. publicspeaking classes. This book has sold 600,000 copies in the last ten years alone, and the total sale of the hard-cover edition is now over 1,000,000 copies. It has been published in some twenty languages and thousands of copies have been sold in these foreign editions. It has not, however, been a book of which the majority of the reading public has been aware.
