Dib Dab Doo and Dilly too (http://www.dibdabdoo.com) This is a British directory that provides access to over 2 million sites that have been classified as appropriate for kids and teens. Developed by a father of 4 children, it also includes a Safety Tips page.

Education World (http://www.education-world.com/) Although there are many sites here are for educators, these sites are primarily aimed at children and teens. The searchable database boasts 50,000 child-appropriate sites, as well as a feature list of subjects and regularly changing sites.

KidsClick! (http://www.kidsclick.org/) This is a great search engine for children. KidsClick! was created by a group of librarians at the Ramapo Catskill Library System as a way for public libraries to guide young users to valuable and age appropriate web sites. You can search by word, first letter of the subject, or use their handy subject areas. All sites are rated by age range and are child-safe.

Yahooligans! (http://www.yahooligans.com) Designed for web surfers ages 7 to 12, with sites selected by the Yahoo! Inc. staff., this is probably the best-known directory for children. You can search either by their grouped subjects, like School Bell, Around the World, or Science and Other Oddities or by your own keyword. It also offers a site of the week, and much more. All sites are child appropriate.
