Why do you need keywords?
Before you dive into your research, it’s useful to make a list of keywords that you will use as search terms. This can help you define your focus, and it will be a useful tool once you start searching, especially if your first search attempts don’t find much that’s useful.

Expand your list by thinking of related terms
Keep in mind that the way terms are used in some fields can be very different from standard everyday usage, and that popular sources such as newspapers or magazines may use different terms than scholarly writing. Reference sources are one good way to start generating lists of these terms for your topic.
As you progress through your research project, keep adding new terms to your list as you find them. Subject headings and article abstracts are particularly good places to look.
