Which of the following is not a primary source? Autobiographies Journal Article Manuscript Encyclopedia

The answer is Encyclopedia.

Here's why:

1. Autobiographies: These are primary sources because they are written by the individuals themselves, offering a first-hand account of their lives.

2. Journal Article: This can be a primary source if it's an original research article where the authors are reporting on their own findings. However, review articles in journals would not be considered primary sources as they are summarizing the research of others.

3. Manuscript: This is a primary source as it is an original document that has not been published elsewhere.

4. Encyclopedia: This is not a primary source. Encyclopedias are secondary sources. They summarize information from a variety of sources and do not contain first-hand accounts or original research.
