The order in which names are expressed vary by culture. In this document, “last name” refers to the surname or family name and “first name” refers to the given name.

If the author is a person, the entry of the name is inverted (last name [surname or family name] followed by a comma and the initials of first names). Give the last name and initials for all authors of a work (up to 20), keeping them in the same order as in the original work. An ampersand (&) is placed before the name of the last author.
