Due to a lack of shorthand classes in my area, I decided to buy this book and teach myself. I read the warnings that this book is not recommended for beginners, but I've taught myself many other skills in the past and figured learning shorthand would be challenging, but possible. When I received the book, I realized that the author assumes you've already read Basic Principles. There are no explanations for what shorthand is, how it originated, or which tools are needed to get started, and I was expecting to see at least a couple of pages covering these topics. I was also disappointed that there are no explanations for any of the material covered in the chapters and that there doesn't seem to be answers for any of the transcription exercises. I returned this book.
