WEB DIRECTORIES  Organize information in groups of related records, i.e., by subject. If you have a very broad or generic search, it might be better to begin with a web directory rather then a search engine. Directories are good for narrowing or helping to focus a broad topic.

SEARCH ENGINES Computer programs used in databases and on the Internet that search for records that match your request. In a catalog or index database, search engines search specified fields (author, title, subject headings, etc.) of each record in the database. On the web, the robots crawl about the web indexing sites, usually looking at URLs, text in the document, or the heading of the document.
