  • Two authors are separated with a comma and an ampersand ( & )
    • Example: Smith, J. D., & Jones, R. L.
  • Three to 20 authors are formatted with commas and an ampersand ( & )
    • Example: Smith, J. D., Jones, R. L., & Harper, S. G.
  • More than 20 authors: List up to nineteen (19) authors; then ellipses (...) and then last author.
