The standard APA guides (see Citation Styles and Guides) will help with articles and other standard sources, but some common business resources are not covered well, and you may not find many examples or specific guidelines. Here are some examples that will help:
APA CITATION FORMAT

For more help, the following guides (developed by librarians) provide additional examples and tips for common business sources. They are all just examples and they may not necessarily all agree, so use what works best for you (and your instructor) and be consistent.
