When reading about history, one needs to keep in mind the origin of the content. For many reasons, the accuracy of the information often differs when the origins differ. As students, we need to seek out the impartial sources from the biased ones. We should recognize the primary sources, like a photo or an entry from a diary which flows directly from the historical event, as opposed to secondary sources, like a movie filtered by a partial view point, leaving out plenty of essential details of the event. Learning about the past entitles us to learn about the whole truth, not the truth persuaded by another historian.
