The financial services area is so deep and so broad, there are enough good books written about it to keep investors busy for a lifetime. If you are an avid reader, here are 10 books you'll want to add to your reading list. If it has been a while since you last picked up a good book, any one of these recommendations is well worth a trip to the bookstore or library.

"The Battle for the Soul of Capitalism" (2005) by John C. Bogle
John Bogle, founder and retired chief executive officer of Vanguard, also long-time advocate for the little person, takes a hard-hitting look at everything that ails the financial system in the United States. From overcompensated CEOs and overpriced mutual funds to Wall Street research scandals and the focus on short-term results over long-term gains, Bogle lays bare the truth behind the wrongs of capitalism. He also highlights the impact that mutual funds and their boards of directors have on the corporate policies of the companies that they run, and he provides a prescription for how stockholders can exercise their will, reclaim the companies they own and put the financial system back on track.

"Conspiracy of Fools: A True Story" (2005) by Kurt Eichenwald
Written by a senior investigative reporter at The New York Times, this entertaining look at the Enron meltdown introduces readers to the rogues' gallery behind the biggest failure in corporate history. From influencing the nation's energy policy to misleading investors and analysts, the audacity, arrogance and greed of these characters is presented in a novelistic style that will keep you reading from the first page to the last.

"Freakonomics" (2005) by Steven D. Levitt and Stephen J. Dubner
Popular, thought-provoking and controversial are all good words to describe this look at how a self-proclaimed rogue economist "explores the hidden side of everything." This is an economics text written for the average reader, not for Rhodes scholars, and it explores a host of real-world topics ranging from violent crime and the hierarchy of drug dealers' networks to backyard swimming pools and baby-naming patterns. "Freakonomics," and its 2009 sequel "SuperFreakonomics,” are interesting departures from the financial services genre's usual fare.

"Bull's Eye Investing" (2004) by John Mauldin
When John Mauldin looked at the future, he didn't see the traditional buy-and-hold methodology as a viable stock market strategy. Mauldin highlights the virtues of absolute return investment vehicles, such as hedge funds and old standbys like gold, as ways to make money in a decade that he predicts will be marked by stagnant markets. Citing factors such as new accounting standards and rising pension costs, he paints a bleak vision of the future and uses a variety of studies to make a compelling argument for his outlook and investment approach.

"A Mathematician Plays the Stock Market" (2003) by John Allen Paulos
Most people know that numbers play a huge role in stock market analysis, and they assume that mathematical genius provides some hidden insight that mere mortals cannot hope to match.

If you like math, you will love this book.

"John Neff on Investing" (1999) by John Neff
The legendary manager of Vanguard's Windsor Fund built his reputation as a bargain hunter extraordinaire. With a contrarian approach to picking stocks, Neff bought low and sold high.
