Types of Evidence
Expert Interviews:  locating and interviewing an expert on your subject is a great idea.  Just make sure that the person you are interviewing is truly knowledgeable about the subject and wants to do the interview.  Be prepared!  Use the Interview Worksheet to guide your interview.

Surveys:  If a group is available who would provide useful information about your topic, conduct a survey and record the results.  Present the results in a table or chart.

Original documents:  Any time you can get your hands on original journals, letters, photographs, or legal documents, you've hit a jackpot!  Not only are they indisputable proof, they are fascinating.  A wonderful database of American historical photos, letters, maps, and documents is the American Memory Online Database from the Library of Congress.

Facts and Statistics: Provable or proven statements or numerical data from trustworthy sources.  Examples:

"Today, 33.4 million people are estimated to be living with HIV/AIDS. Of these, 32.2 million are adults. 13.8 million are women, and 1.2 million are children under 15."

Anecdotal:  a usually short narrative of an interesting, amusing, or biographical incident.  Anecdotal evidence works like "show-not-tell" writing--in some cases, it is more effective than facts or statistics.  For example, if you wanted to help prove the thesis, "The war in Kosovo is one of unfair brutality," you might use the following anecdote:

To find anecdotal evidence, you'll need to READ!  Scan newspapers for articles about your subject and look for quoted passages.
