Web Search ToolsSubject Directories generally involve human selection: the websites included in a directory usually have been examined, selected, and categorized by a person. The categories in a subject directory are hierarchically organized. In general, one finds fewer hits in a subject directory, but the hits are usually better ones. Directories are most useful when browsing for information about a general subject. Start with a likely broad subject or topic; then drill down through the subtopics. A few subject directories to try:
