KidsClick! (http://www.kidsclick.org)

Parents need to know that KidsClick!, a site directory and search engine created and maintained by librarians, links to some topics that may be considered controversial, but the site's policy is to catalog resources that provide objective, age-appropriate information so kids can understand these topics when they come up in the news. The site's administrators won't list sites that collect private information (such as full names and phone numbers), charge a fee, are product-driven, or promote violence, hatred, or illegal activities.
