Referencing information for multiple authors
The first author in an author line is assigned to the built-in attributes author, email, firstname, etc.
Subsequent authors are assigned to the built-in author attributes, but the attribute names are appended with an underscore (_) and the numeric position of the author in the author line.

The built-in attributes used to reference their information are appended with the number 2, e.g., author_2, email_2, lastname_2, etc.
