Some textbook! . This is the longest textbook I have in my collection and it is also a bad investment book at that. I know some readers really enjoyed the detailed explanations, but the book was too detailed and wordy for me. Many of the explanations are unnecessary and examples can be simplified to get to the core of the problem/concept and drive at a much stronger intuitive understanding. But this book doesn't do that. It is cluttered with definitions and wordiness that kill the intuition one could get by reading a more concise, straightforward text. A really good book is Investment Science, by David Luenberger. Although his text assumes you have some background in calc/stat/probability theory, the writing, examples, and organization is far superior. You'll actually begin to understand how investment really works, without getting bogged down by the numbers, terminology, and jargon

A bit thin on... . Reading this pamphlet is one way to spend 20 minutes. However your 20 minutes would be better spent searching online for a book with a bit more "meat" on Japanese carriers

Nice Picture Book . Basically Diamond Baratta Design is a lovely picture book - If you are a decorator or decorating your own home it can be a good source of inspiration or at least a few ideas .If just a fan of decorators it might disappoint as there is little substantive background information about their careers and philosophy. A good mate to this volume would be a book about Dorothy Draper as the Diamond Baretta team follow through on many of her ideas about color and scale.
