What are some examples of Secondary evidence?

Secondary evidence refers to information that is not directly obtained from the original source but rather derived from or based on primary evidence. Examples include summaries, analyses, or interpretations of primary data, such as journal articles reviewing research studies, textbooks that compile and explain findings from various studies, and news articles reporting on events based on eyewitness accounts. Additionally, legal documents like affidavits or witness statements can also serve as secondary evidence when they reference primary sources.
