Here are some simple tips to help ensure that you access high quality information on the Internet. Look for the qualifications of the people publishing the site. Most responsible sites will indicate the date the site was originated and the last revision made. Be aware of bias.
Some sites are designed to provide information, others are businesses selling products or services.
Be careful if the motive of the web-site is to sell a product or service. A good web-site will be easy to use and to understand.
