1. Author: Full name(s) of authors (Lastname, Firstname. All other authors Firstname Lastname).
2. Article Title: and subtitle, with all major words capitalized(surrounded by quotation marks)
3. Journal Title: with all major words capitalized (in italicized characters), issue information (volume title and/or number) and publication date in parentheses and ended with a colon afterwards “(month, year):”.
4. URL/DOI: (for online publications).

 As with all other citations, the publication date of the reference will be placed directly after the title when using Author-Date style.
