I do a fair amount of public speaking and have found this book very helpful in many respects. It does an excellent job of covering the basics, includes some great tips that you might not think of on your own and also introduces some advanced topics without overwhelming you with lots of detail.Like most of the "For Dummies" series, the book has an encouraging tone and is written in a humorous or light manner. It's an easy and pleasurable read and I believe everyone interested in public speaking would pick up something useful from it.
