What if a Source does not identify its Author?
When an author's identity is withheld, as is occasionally the case with newspaper articles and Internet sites on the World Wide Web, try to identify the sponsoring organization or publisher and proceed from there.
If you're working with a print source that does not list an author, consider the nature of the publication: is it a nationally respected newspaper or a supermarket tabloid? Is it a brochure or pamphlet published by an organization recognized as a leader in its field?
On a Web site, look for the organization or publisher's contact information. You should be able to find something relevant, even if it is a disclaimer, on the "home" or "about" page.
