Subject Directories include human-selected web sites sorted into categories. Directories are good places to start your search.
Search Engines use robots or "spiders" to crawl the Web to find sites to put in an index. Though search engines have similar parts, they don't all find the same things. Try using more than one.
Meta Search Engines search several search engines at once, so you can cover more ground.
