Keywords are important words/concepts used to find resources (books, articles, pictures of cats, ect.).
Your first keywords will come from your research question.
You can get more keywords from:
Choose simple but clear keywords and connect them with boolean language (AND, OR, NOT)
|AND||Searches for places where both keywords appear together|
|OR||Searches for either of the keywords. They might be together or they might not.|
|NOT||Searches for places where the first keyword appears without the second.|
