Step 1: Start your search process by brainstorming a list of keywords that describe the main concepts of your topic or question.
Step 2: Use these keywords for your initial searches. (For variants on a word, use $ as a wildcard: e.g., hindu$ = hindu and hindus and hinduism, etc.)
Step 3: Pay attention to the subject headings in the Acorn record. These can be used to refine your search. (You may also want to try a SUBJECT begins with search in Acorn with your keywords.)
