There are two different ways to look for useful Websites. One way to is rely on directories , and the other is to use search engines . Directories are lists of Internet sites arranged by subject. They are created by people who review the sites, decide if they are worth linking to, and choose which subjects to list them under. Directories are selective in what they list, which means that they offer fewer sites to choose from than search engines do.
Some directories have a rating or ranking system that is explained at their site.
Directories are easy to use because you can browse through the categories. Though this can be tedious, it solves some of the search vocabulary problems discussed in OWL 4 . Most directories now have a site search feature, which can help you zero in on what you are looking for. Some directories have links to search engines, and the major search engines have directories on their homepages, compiled and categorized by human editors. If you are new to the Web or just want to find some good sites on a subject, a directory is probably your best place to start.
