Information on public companies is considerably easier to locate than information on privately-held companies. In the United States much of the information you want to access will be readily available on various Internet sites or accessible through a local library with a little effort. The most obvious obvious place to begin are those basic sources mentioned in the directories section of this guide. However, they often don't have the depth that is needed, so there are other places to look. I have included only a small list of sources for information on public companies - there are many to choose from. The directions below are geared to finding information on US public companies, foreign company research is treated as it's own topic later in this guide.
