The business databases are a good place to start when you need a mix of articles about a company, product and consumers. Business databases include full-text of general business publications (Business Week, Inc., Fast, WSJ) in addition to trade and industry publications (New Media Age, Publishing Executive, Information Week) and journals (Harvard Business Review, Journal of Brand Managment, Customer Relationship Management).
Check with your professor about the preferred style manual. Most faculty in the Cotsakos College of Business use either APA ot Turabian/Chicago. Note: the business databases also provide citation assistance.
