The Yahoo! Directory and Yahoo! Search work together to bring you the information and resources you are looking for.
Yahoo! Search returns a list of webpages containing the words you entered. These results are a combination of relevant webpages and websites provided by Yahoo! Search and the Yahoo! Directory.
The Yahoo! Directory is a human-created and maintained collection of websites organized into categories and subcategories. Yahoo! editors review these sites for potential inclusion in the Directory, and to evaluate the best place to list them.
For example, you can see a full listing of general sites related to dogs by visiting Yahoo!'s Dogs category. Sites about more specific dog-related subjects are listed under appropriate subcategories.
