Use databases to find articles on your topic. These databases are the best place to start.
Tips: When searching databases, use AND, OR, and parentheses to focus your search.
The asterisk * symbol will search for all variations of a word. For example: basket* will search for baskets and basketry. Using quotes will search for a phrase.
Combine synonyms with OR and put them inside parentheses, like this:
"human growth hormone" AND (doctor* or nurs*)
Here's another example:
("pituitary gland*") AND (grow* or "blood pressure")
