When searching for business information in secondary sources, it is often good to start by thinking about who else might have a reason to collect the same type of information you are seeking. Most business information comes from three types of sources:
Various branches of government provide a wide range of data and facts essential for business operations and analyses. These include, among many other things, patents, tax laws, Security and Exchange Commission (SEC) filings for publicly traded companies, economic census data on businesses, population census data on markets, and household spending data.
Almost all companies have websites as well as media or public relations personnel who disseminate information about companies and their products--and sometimes their competitors. Just remember that companies may be somewhat selective about what they choose to share and how they position the information they do release to the public.
