Primary sources are documents that contain first-hand information or original data on a topic. They are works created at the time of the event, by a person who directly experienced or reported on it at that time. They can come in many formats including: letters, diaries, journals, hand-written notes, newspaper articles, government documents, ephemera, or magazines.
Secondary sources are documents that are one step removed from the original source, event or experience. These works may describe, analyze, evaluate, or be derived from or based on a primary source. Secondary sources may critique or interpret a primary source. Examples of secondary sources include literature reviews, biographies, textbooks, or articles that explore documents from the past.
