Finding Information on the Internet
Evaluating Web Information
There is a wide variety of information available on the Web, making it one of the most powerful tools for doing research. But unlike most other traditional forms of information, no one is required to check Web information before it is posted and made public. As a result, the quality of information on the Web ranges from very high to very poor. It's up to you evaluate, or judge the value of, the information you find on the Web to make sure if it seems trustworthy.
The first step in evaluating Web information is to know the kind of site you are accessing. You can tell this by paying attention to the domain of the address. Different domains often will contain different kinds of information, even on the same subject. Here are some of the most common domains:
You can generally expect the information on .gov and .mil sites to be accurate. The information on .edu sites is generally accurate. However, if an .edu site also has a tilde symbol (~) in the address, it is a personal page and needs further evaluation. Sites with domains of .net, .com, and .org also require more evaluation.
The CARS Checklist
You can use the CARS checklist (Credibility, Accuracy, Reasonableness, Support) to help you evaluate information on the Web. Not every Web page will meet every part of this checklist. But familiarizing yourself with the items on this list will help you better and more quickly evaluate the information you find.
