The Neatest Little Guide to Stock Market Investing

For a beginners guide to investing, including terminology and the strategies of successful investors, I highly recommend The Neatest Little Guide to Stock Market Investing by Jason Kelly. This is the book I started with, and it gave me the foundation to progress further. Whilst its focus is on American companies and markets, much of the content can easily be translated globally.
One Up on Wall Street

One up on Wall Street by Peter Lynch is a wonderful introduction to the personal qualities required to be successful in investing. This book, along with Beating the Street (also by Lynch) is probably the most accessible book I have read on the subject. He discusses many complicated ideas in a simple and often humorous way.
The Intelligent Investor

Benjamin Graham's The Intelligent Investor is the more accessible version of his earlier work, Security Analysis. Considered the grandfather of value investing, Graham's work in these two books helped lay the foundation for modern investment practice. The Intelligent Investor is an absolute must-read for anyone who understands the basics, but is seeking a deeper understanding of the true nature of value.
What Works on Wall Street

For any investor with a value/quant tilt, James O'Shaughnessy's "What Works on Wall Street" should be required reading. In meticulous detail, O'Shaughnessy looks at historic returns of popular value metrics, such as Price/Earnings, Price to Book and Price to Sales. Now in its fourth edition, it empirically proves value investing works.

The Most Important Thing

I'm a big fan of listening to Howard Marks whenever he speaks, and The Most Important Thing illustrates why. Marks reminds us that investing is a discipline, that all the excitement and buzz must be ignored if one is to stay focussed. I recommend this book to anyone looking to guard themselves against losing their discipline.
The Most Important Thing
100 Baggers: Stocks that Return 100-to-1 and How to Find Them

As the title suggests, this book goes about trying to discern exactly how one would find a stock or stocks that could return a 100-fold increase in your original purchase price. It's obviously not as simple as reading this book, but there are some excellent pointers.
Contrarian Investment Strategies

I'd place Contrarian Investment Strategies up there with Jim O'Shaughnessy's What Works on Wall Street in terms of the value it provides to any investor who thinks from a quantitative perspective.  This book covers a wide range of investment theory, from technical analysis to thoughts on risk, value investing to stock market psychology.  One of my favourites.
Against the Gods

Though not specifically about investing, Against the Gods traverses the history and development of thoughts and attitudes towards risk and risk management. Littered with practical and historical examples, it isn’t the easiest read, but it will most definitely give you a deeper understanding about the notion of 'risk'.
Dear Chairman

Let me first say that Dear Chairman is absolutely fantastic.  It is also many different things.  On the face of it, it's a collection of case studies of activist investors, and their battles with various boardrooms.  Beyond that, it is a history of the development of shareholder activism in the twentieth and early twenty-first century.  Beyond that, it is an exploration of the changing nature of public company boardrooms.  Look even further, and it is an investigation into the evolution of stakeholder and shareholder interest across corporate America.  Just brilliant.
The Little Book That Builds Wealth

The Little Book That Builds Wealth should be integral to any investors library.  The book is focused on helping identify companies with sustainable competitive advantages, or 'moats'.  Dorsey begins by looking at the different types of moat, before explaining how to identify quality companies that possess one or more of them.  Lastly, there are two chapters devoted to buying at appropriate valuations and knowing when to sell.  A short read, but highly valuable.
