Reference sources (sometimes known as tertiary sources), usually give you a broad overview of a topic. You can look up answers to general questions here, and start to decide what specific questions you want to ask in your own research.
You'll also start to gather keywords / search terms on your topic, which will be very handy when you start to search for books and articles on your topic.
