Information About Websites

When searching for web sites, keep in mind:

Who is the author of the website? Is the author credible?
What is the author's agenda or bias? Is coverage of the issue balanced? If not, can you find other websites that present the opposing view?
Be wary of the site's domain or URL. Professional societies usually have a domain of .org; government sites usually have a domain of .gov.
Be careful of hoax sites like Dihydrogen monoxide, Great Lakes Whales, or Pacific Northwest Tree Octopus.
Why was the article posted on a website instead of published in a professional journal?
