START WITH THESE
OTHER DATABASES
The building block of a library database search is keywords. Keywords are central ideas or terms within your research question or problem.
Once you have your keywords identified (2-3 is a good place to begin), you then need to connect them together in a way the database understands how to search. This is done using the Boolean search operators AND, OR, and NOT. Connecting keywords using these search operators creates a search string.
Do not limit your search to just one database. Instead look at a variety of databases both subject specific and interdisciplinary to make sure you are viewing the full scope of literature published on your topic.
