Do you trust that your clients will pay, your partners will stick to their agreements, and your competitors aren't doing anything that affects your company's well-being? In the world of business, trust often depends on how much you know about the companies with which you're doing business.
Where you look for that information and what you find typically depends on the size of the company you're trying to investigate and whether or not it's publicly owned. Small, privately owned companies are more difficult to research because they aren't required to make public much information.
One of the first places you should search for information on private companies is in your local newspapers. Don't limit your search to one paper or to the front section. Comb the real estate and business sections and, if the paper has one, the local gossip column. Most newspapers today have Web sites equipped with search engines, which makes research easy. But some papers don't archive their full publications on the Web, while others archive only two weeks' worth of material. Some library legwork might be called for.

Research on publicly owned companies is much easier to obtain. The reason: By law, public companies must reveal their strategic plans, annual profits, investments, and losses. Electronic Data Gathering and Retrieval System (EDGAR for short), of the Securities and Exchange Commission, is a treasure trove of information on public companies. Edgar includes annual reports as well as offerings to sell stock.
