A Web directory is a static listing of Web links, usually built up by human editors. Directory links are usually described in a short paragraph, and categorized by subject. (This is as opposed to a Search Engine, which uses an automated database rebuilt regularly by a computer program, or spider, automatically following links - any descriptions are taken from the page text). The Open Directory you are using right now is an example of a Web directory. This category contains Iran related directory Web sites in English or English and Persian.
