The Research Process is a cycle, not a straightforward step-by-step progression. There are steps involved, but they can be repeated as you learn more about your topic and perhaps change the focus of your research.
Librarians can be especially helpful in two aspects of the information-gathering portion of the research process:
WHERE to search: recommending appropriate databases and other research tools for your particular topic
HOW to search: coming up with good terms to use when you use these research tools, and arranging those terms in ways that will give you the best results
