DISCIPLINE-SPECIFIC RESEARCH SOURCES. Each discipline (Business, Human Services, Education, Emergency & Disaster Management, etc.) uses research in specific ways. For example, some disciplines rely more on peer-reviewed articles than others. Some rely more on statistics and data than others. Some use information published over a long period of time; others need information from a much shorter span of time, even from just within the last year. Some may require more visual research, while others require textual research. Part of becoming a professional in your field is learning about the research sources specific to your field.
