Evaluating Objectivity

Goal: Find sources to address all sides of an issue.

Does the writer have a strong opinion on the issue?
Examples: NARAL Pro Choice America has a very different view of abortion than National Right to Life.
Many print and electronic sources have a reputation for a particular political slant.
Examples: The National Review and Fox News are generally considered to be conservative, while Mother Jones and NPR are generally considered to be much more liberal.
Is that point of view obvious?
Example: The white supremacist underpinnings of "Martin Luther King, Jr.: A true historical examination" are not revealed unless the "hosted by" link is followed.
Is the source trying to convince you to DO something
Example: Most commercial Web sites want you to buy a product or service. Their quality data should be balanced with information from a consumer oriented source.
