I took some time recently to look at Evidence Explained (the website and the book) to see just how to format Newspaper.com source citations based on that citation style. I had been doing it incorrectly--I had almost all the correct elements in what I had been doing just not in exactly the correct order. Then, I wanted to adapt the source citation for WikiTree. This is what I came up with... (Critique is welcome.)
1. Author name with given name middle name or initial then surname, if any (otherwise start with article title)
3. “Title of Article in Quotation Marks with comma inside final quote mark,” For WikiTree, put all this inside square brackets with the URL of the actual article to create link, e.g. [https://www.newspapers.com/clip/60278554/obituary-for-j-b-turner-aged-58/ “J. B. (Buell) Turner (Obituary),”] If article has no title it is okay to create one based on the text.
4. Name of the newspaper in italics (on WikiTree italics are created with two single quotes at each end of element) with place name in parentheses as needed
6. Date of publication day month year
8. Page number abbreviated a p.
10. Columns abbreviated as cols.
12. The words “image copy” (no quotes)
14. Name of the repository (Newspapers.com, Ancestry.com) in italics
15. Open parenthesis
16. URL of website (i.e. http://www.newspapers.com
18. Date of access as “accessed day month year” (no quotes)
19. Close parenthesis
