The book, The Craft of Research, has several questions you might want to consider asking as you continue with your focused topic. They are:
- Ask about the history of your topic.
- Ask about its structure and composition.
- Ask how your topic is categorized.
- Turn positive questions into negative ones.
- Ask what if? and other speculative questions.
- Ask questions suggested by your sources.
When you are done, evaluate your questions and look for questions that make you look at your topic differently.
