New World Encyclopedia is a free web reference containing thousands of selected articles about human knowledge. It is aimed at teachers, students, and general readers, including people reading at late high school or early college levels. Coverage includes philosophy, religion, history, biography, political science, social sciences, geography, physical and life sciences, and arts, music, literature, sports, and leisure. Articles are arranged alphabetically, connect to related entries, and support keyword searching through a custom search engine. Scholars and editors supervise articles and review facts, grammar, and values. Readers can submit feedback, but editors and staff decide whether to change entries. The site uses MediaWiki and a SphinxSearch-based custom search system, and provides text and images. Pages document links to Wikipedia for imported article histories and Amazon ISBN links that may earn referral fees. Text contributions use Creative Commons Attribution-ShareAlike 3.0 and GNU Free Documentation License terms, subject to reuse rules; fair-use material and some media may have separate restrictions. Since 2009, the project says it has relied on advertising and donations.
