What is a primary source?

A primary source is defined as an original document or firsthand account from the time being studied. This type of source offers direct evidence or direct testimony concerning historical events, people, or phenomena. Examples of primary sources include letters, photographs, diaries, official documents, artifacts, and eyewitness accounts. These materials are invaluable for historians and researchers because they provide insight into the context and perspectives of the time.

In contrast, other choices relate to secondary sources or interpretations rather than primary evidence. For instance, summaries and analyses made after an event, compilations of information from various accounts, and scholarly interpretations do not provide direct insight into the original events. They are useful for understanding context but do not serve as primary sources themselves. Therefore, the definition of a primary source as an original document or firsthand account (the correct answer) is pivotal to understanding how historical research is conducted.
