Wikipedia: History

History is often used as a generic term for information about the past, e.g., as in "geologic history of the Earth". When used as a field of study, history refers to "human history", which is recorded past of human societies. The term "history" comes from the Greek historia, "an account of one's inquiries," and shares that etymology with the English word story. Historians use many types of sources, including written or printed records, interviews (oral history), and archaeology. Different approaches may be more common in some periods than others, and the study of history has its fads and fashions (see historiography, the history of history). The events that occured prior to human records are known as prehistory. There is a very large amount of historical information available and more than one way to classify it for easy navigation.
