Wilson, 1999).

Groups as Authors

The names of groups that serve as authors (e.g., corporations, associations,
government agencies) and not widely known are usually written in full each time they

appear in a text citation. If the organization has a well-known abbreviation, include

the abbreviation in brackets the first time the source is cited and then use only the
abbreviation in later citations (e. g. UN for United Nation).
