I believe this is primary source
If the source is like a artifact, a diary, journals, speeches, memoirs, autobiographies or anything that was created by the witness of the event like for instance, a personal narrative
(Sorry this is the best I can explain a primary source, an example would be the diary of anne frank)
If the source is a interpretation version or a work that analyzes a event it would be considered secondary source
(An example would be “A book about the holocaust” because the author wasn’t there to witness the event, the author is just writing a biography on it)
I think an easy way to remember this would be
Autobiographies (writing about your own life) - primary source
Biography (Ex. A book about blah blah blah) - secondary source
