Most information is published with a specific purpose in mind. It might be simply to inform readers. It might also be to persuade, present an opinion, or sell an idea, product, or service. When we assess the purpose of a website (or even an article or book), we try to determine whether the author and/or publisher has a bias or particular point of view. Point of view is usually a large factor if you are researching social, political, or artistic issues. The Web is rife with opinions and bias, making it an excellent source for controversial topics. It seems everyone on the Web has an opinion about something. There is nothing wrong with a source taking a stand as long as you are aware of it. The problems come when you don’t realize the information is biased.
