Where can I find all public companies' information?
Moody's is now Mergent Online. It's no longer being printed, and must be accessed digitally. In order to browse the database, check with your local public library or university to see if you can get access. (A University will probably require you to visit for access).  Another good tool is Value Line Reports. They are printed information sheets on public companies that are updated regularly, and are convenient for browsing and for comparing securities. Again, check your local libraries.  A lot of the public information you may be looking for can be found on Yahoo Finance, for free, from home. Yahoo finance, will give financial information, ratios, news, filings, analysis, all in one place.
