Where to get equity data to backtest

[exotic]

I want to backtest some trading strategies (esp magic formula descriped in Little Book that Beats the Market by Joel Greenblatt), and this will require daily individual stock data (closing price, EBIT, working capital, net fixed assets, market cap, debt) spanning over 20 or 30 years, for a large universe of stocks (including small/mid-cap).

Does anyone know how I can acquire this data online or on bloomberg without having to do it ticker by ticker. Thanks.

Good data is usually not free. If you are a student, you can try your library to see if they have subscription to any of the data provider.
