Source analysis is the careful study of historical sources to understand their meaning and accuracy. Historians and students examine different types of evidence such as documents, artifacts, and images. This process helps build knowledge about the past.

During analysis, questions are asked about who created the source, when it was made, and what it shows. A photograph, for example, can reveal clothing, buildings, and daily life. Written sources can show opinions or recorded events.

Source analysis also includes checking for bias and reliability. It helps researchers compare information and understand how sources relate to each other.
