So why is the book so successful? First, Klarman is an extremely successful money manager. Second, the print run for the book wasn't that big. Third, the book has been out of print for about twenty years, based on my understanding. Fourth, because of all these reasons, the book has become a collector's item as opposed to a book.
And what's the book all about? Value investing, which he covers in extensive detail. He also continuously promotes the philosophy of maintaining a margin of safety. This hardback book is 249 pages long and is published by HarperCollins. Surprisingly, it ranks #23 in the category of Books > Business & Investing > Investing > Bonds.
You probably don't want to buy the book as a gift for someone (you would hate to find out it ended up in a charity book sale). But if you are interested in it for yourself, and price is no object for you, you should get Margin of Safety: Risk-Averse Value Investing Strategies for the Thoughtful Investor.
