Denne kilden sier også noe i den duren om APA-stilen:
Unknown Author: If the work does not have an author, cite the source by its title in the signal phrase or use the first word or two in the parentheses. Titles of books and reports are italicized or underlined; titles of articles and chapters are in quotation marks: A similar study was done of students learning to format research papers ("Using APA," 2001).

Her kan man taste inn informasjonen man har, velge stil, og så viser den rett format. Også den ville valgt tittel på artikkelen heller enn Wikipedia i tekstreferansen.
