Start with Reference Resources
Reference works are considered tertiary information sources. Tertiary sources include encyclopedias, dictionaries, bibliographies and other reference materials that provide broad overviews of particular topics. Where secondary sources summarize and interpret an event or phenomenon, tertiary sources summarize and interpret other resources.
Reference tools give you good background information on the topic you are investigating. Questions to ask include: 1.What are the key issues; 2.What terms are being used? Learn the lingo; 3.What are the relevant and necessary primary sources?; 4.Who are the key people?; 5.What are the key works?
Being able to answer these questions will help you build a good conceptual framework for your topic.
