** Graham & Dodd's Security Analysis, Fifth Edition; Cottle, Murray, Block; McGraw-Hill
** Financial Valuation: Businesses and Business Interests; James Zukin, editor; Warren, Gorham, and Lamont
* It's When You Sell That Counts; Donald J. Cassidy; Irwin
* Against the Gods; Peter L. Bernstein; John Wiley
* The Shareholder Value Myth; Lynn Stout; Berrett Koehler
* Mydia Myth Makers; Benjamin Radford; Prometheus Books
* Strategic Intuition; William Duggan; Columbia Business School
* Models.Behaving.Badly.; Emanuel Derman; FreePress
* Profiting from Chaos; Tonis Vaga; McGraw-Hill
** The Intuitive Investor; Jason Voss (me); Select Books
* Analysis for Financial Management; Higgins; Irwin McGraw-Hill
* 101 Business Ratios; Gates; McLane
** Financial Reporting and Statement Analysis; Clyde P. Stickney; Dryden
** Financial Management: Theory and Practice; Brigham and Gapenski; Dryden
I could go on as there are so many choices. But those are among my favorites. Those that I gave a '**' are the ones I like the best and feel will give you a well-rounded, non-business school, education.
Best, very best wishes for success!
