"The problem? 11,000. That is the number of business books published in the United States every year. Placed one atop another, the stack would stand as tall as a ninety-story building. Recommendations reduce the noise. Suggestions from friends and colleagues are best, because they know you and your circumstances. Reliable media sources that regularly review business books, like The Wall Street Journal and BusinessWeek, are also a great source for slimming the pile. Blogs, tweets, and Facebook statuses can be just as valuable. Online booksellers offer customer reviews on their product pages, and physical bookstores have helpful employees who can help you find a book Worthwhile as they are, recommendations merely reduce the size of the pile. Our next step is to determine which book is right one."
