Web Directories are sometimes confused with 'search engines' - and vice versa, but they are not the same thing. The biggest difference is probably that a Web directory is maintained by humans (in most cases) instead of software and the Web sites are organized by subject.
The searcher looks at sites organized in a series of categories and menus. 'Web directories' are usually much smaller than search engines' databases, since the sites are looked at by human eyes instead of by 'spiders'.
Web directories are usually dedicated to specific niches/subjects, however there are many which are quite general - they list pretty much anything.
There are also paid directories and free directories. In paid directories, it costs a fee to have a web site included in that directory. In free web directories it doesn't cost anything to have a web site included.
Below are some examples of web directories:
