What are the Author's Professional Affiliations?
Expect differences in opinion among leaders of various political parties or types of organizations. An editorial about preserving wetlands written by the president of the Sierra Club will be a lot different than one written by a lobbyist for a real estate organization.
Although it's rare to find a complete listing of an author's affiliations, many periodicals, both in print and online, provide brief descriptions of an article or column's author. Check these descriptions for clues about an author's affiliations.
If you are interested in learning more about them, consider searching the World Wide Web. An increasing number of authors have created home pages on which they list information about themselves, their educational background, professional experience and personal interests.
