The Usefulness of Subject Directories

Description: Subject directories are built by human hands instead of by “spider” programs scanning web pages. The results are often sorted by subject instead of ranked by a computer. The results given by a subject directory can be a great deal more relevant to a given search, even though the database of searched web pages is somewhat smaller than the average search engine.
