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 events that occurred prior to human records are known as prehistory.
A criticism of history as a field has been that it has too narrowly focused on political events or on individuals. Deeper and more significant changes in terms of ideas, technology, family life and culture have received too little attention. Recent developments in history have sought to redress this.
It should be noted that the term 'History' is not used to represent the entire history of our species, but events that have occurred since the agricultural revolution and the appearance of civilizations, the past 10,000 years or so. Events that occur before this time are lumped together under the term prehistory (which covers more than 99% of our species' time on this planet), despite no change in the genetic make up of pre and post-historic humans.

Main article: Historical classification
A very large amount of historical information is available, and several different ways of classifying it are given at the main article.
By ideological classification (historiography)
Although there is arguably some intrinsic bias in history studies (with national bias perhaps being the most significant), history can also be studied from narrow ideological perspectives, which practitioners feel are often ignored, such as:
A form of historical speculation known commonly as virtual history, or "counterfactual history", has also been adopted by some historians as a means of assessing and exploring the possible outcomes if certain events had not occurred or had occurred in a different way. This is somewhat similar to the alternative history genre in fiction.
