One of the first steps in any research project is looking at your questions and determining what type of information will answer that question. Many of your sub-topics involve finding factual information to answer some questions. How do you know when you need to find factual information?
Questions that begin with Who, When, or Where tend to require a factual answer. When you need to know the details of a particular event, the people who were involved, who a particular person was, or where something took place, you need to find factual information.
There are many sources of factual information, and where you look will depend on the event, person, or place in question. Does your question involve current or historical events or people? Is it asking for a definition of a term, genre, or technique? Do you need to know what certain people said or wrote about an event?
For some information, particularly about particular theater or dance terms, movements, genres, people, and pieces, you'll want to turn to encyclopedias and other reference sources. Encyclopedias provide brief articles about a wide variety of topics. Wikipedia is a type of encyclopedia: You can look up particular topics, people, and places, and find enough information to give you a starting point and a beginning understanding of the topic. There are many encyclopedias that cover specific subject areas.
