What Are Your Keywords?
When you are searching for books and articles on your topic, you will need to select some keywords. They are like the main ideas in a sentence. The words in your research question are perfect starting points. For example, What are the causes of global warming? But there are other words that might help you. Terms that mean the same thing ( synonyms) are also worthwhile keywords. Global warming is sometimes called climate change and drug use among athletes is sometimes called doping. Using different terms to locate information will give you greater results.
