You should join the trade association for your market type of business. Check the Encyclopedia of Associations and National Trade and Professional Associations in the United States for a listing of trade associations for your type of business. A trade association is made up of people who are in that type of business as well as people who are suppliers to businesses in that trade. The trade association and its members have a wealth of information that they have gained via extensive experience in markets that you will serve with your business. What they know and what you can learn from them will definitely increase your odds for being successful.
Most trade associations offer magazines or newsletters.
They also schedule exhibits and speakers on a variety of topics to assist their members. You should also gather information about trends for your industry's products, services, expenses, advertising, credit policies, rate of growth, foreign factors, current laws, pending regulations, technological changes, etc. U.S. Industrial Outlook, published by the U.S. Department of Commerce, has a section on emerging industries. The Business Periodicals Index and The Magazine Index may also identify articles about markets that you will serve with your business. A Directory of Market Research Reports, Studies, and Surveys may also be helpful.
