IPOs

Disclosure
For a price, Disclosure's Global Access offers the Edgar filings and other reports on public companies. Like most for-pay Edgars, it's generally more organized than NYU's free site.

Edgar Online
This commercial site organizes the SEC filings better than NYU's Edgar, with up-to-the-minute updates and analysis. Some of their services are free.

Hoover's Online
Search the Corporate Directory, a database of more than 10,000 companies (which is free), and the Company Profile Database (which requires a subscription).

IPO Central
Take your pick from the initial public offerings of young companies just getting their feet in the water.

NYU Edgar
New York University puts the SEC filings, a giant government database, on the Web, for free. But if you don't know a 10-Q from an S-1, take a look at Edgar Online (above) instead, for better explanations.
