Find a focus: Develop a manageable topic - not too broad, not too narrow.
Frame your topic idea as a research question. For example: How does proper timing of nutrition affect athlete endurance?
Identify needed information: Decide what sort of books, reference sources, and articles will help you thoroughly research your subject. Consider current books, eBooks, and journal articles, and decide if you need to interview experts on the subject or develop your own research study.
Create your research strategy: List keywords, synonyms and related terms, subject terms, and descriptors for your research. Decide what sort of resources are necessary to support your research.
Review your findings: Look at the quality, quantity, and relevance of your research. Are your sources credible? Does your research answer your question? Are you finding relevant facts and quotes? Identify the gaps. Ask yourself: What else do I need to know? What seems to be missing?
