Before you can start any research on your topic, you must have a background knowledge of it. Books and websites can provide you with that knowledge.
This is important because:
Remember, background information is always a starting point for research, not an ending point. Your paper will be supported with scholarly or primary or secondary sources, not background information. If you are not familiar with what constitutes a scholarly source - see #4: Read & Evaluate. DO NOT cite to background information!
