The Single Best Investment: Creating Wealth with Dividend Growth (2006) by Lowell Miller
This book helped convince me that dividend-growth investing is a good long-term investing strategy. The author provides an excellent overview of dividend-growth investing, explaining how it works and how to do it. The idea of creating your own "private compounding machine" through a combination of dividend growth and reinvestment is one of the most sensible investment ideas I have ever read. There is a decent discussion of how to go about building and managing a dividend-growth portfolio, although I found the chapters on fundamental analysis (valuation) to be more useful than the chapter on technical analysis (chart reading). There are two informative appendices: the first reviews some academic studies and performance results that are relevant to the strategy and the second describes different categories of dividend-paying stocks that might be included in a dividend-growth portfolio.
Note: I read this book in July 2011.
