Subject headings allow you to search for resources on a particular author or topic and are often more productive than keyword searches.
Keyword searches work best if you have multiple concepts or topics. Think of the words that best describe your topic and then connect them with the boolean operators AND OR NOT.
One strategy to find books on your topic is to use a keyword search to find relevant subjects that you can click on to find more books on the same topic.
