Directories of private equity firms

I thought I'd share two sources for a question I hadn't gotten before. A patron asked for a directory of private equity firms and angel investors. With Louise's help, we identified two print sources that would work for this:

• Galante's Venture Capital and Private Equity Directory (not at Baruch, but at SIBL)
• Pratt's Guide to Venture Capital Sources (Baruch has 2007, SIBL has 2008)

I tried D&B $Million Database, but found that the relevant SIC and NAICS codes weren't finely grained enough to search for just private equity companies.
