Wikipedia provides a nice general overview of your topic. You can also use the bibliography to find more sources. And it's GREAT for generating KEYWORDS to create new search strings.
To get the most relevant search results, you need to generate keywords on two levels.
1) Find keywords which are SYNONYMS (the terms in blue).
2) Find keywords which explore your angle (the terms in purple).
3) Mix and match the keywords which are synonyms and the keywords which explore your particular angle to create new search strings and search again. Try different keyword combinations and search again until you get RELEVANT results!
Remember, DON'T GET MARRIED TO YOUR SEARCH TERMS. Mix & Match!
