In universities, government agencies, and the business world, field research can be as important as library research. In some majors, like education or sociology, as well as in service-learning courses, primary research projects are common. Even in the writing projects covered in Chapters 2–9, observations, interviews, and surveys may be useful or even necessary. As you consider how you might use field research in your writing projects, ask your instructor whether your institution requires you to obtain approval, and check Chapters 27 and 28 for information about citing interviews you conduct yourself.
