Here is the link to a Hoover's profile of Carlyle Group--the investment firm where your money isn't welcome unless you have at least tens of millions to place.
It's about the only free thing of value you will find at Hoover's online. Still, since it isn't investigative reporting but rather a pro-company description, it actually has more info. I'd disseminate the whole thing, but Hoover's threatens legal action.
