Klexikon vs Lex – Danmarks Nationalleksikon

Klexikon is a free German-language online encyclopedia written for children roughly 6 to 14 years old. Its editorial approach favors clear wording, short sentences and content suited to young readers. The project says Klexikon contains more than 3,500 articles, with a further 1,500-plus in MiniKlexikon, where the language is especially simple for beginning readers, German learners and children with additional learning needs. Articles use child-appropriate images from Wikimedia Commons, and the editorial guidance calls for at least one image per article. Some articles also include Tagesschau explanatory videos. The web site is available without a login; the project describes it as ad-free and says it does not collect personal data. Article text uses the Creative Commons Attribution-ShareAlike license, which requires attribution and the same license for reuse. Children may submit article requests, questions or error reports. Adults can apply to contribute by email and normally receive an account after an introductory course; new contributors must be at least 18. Klexikon also offers workshops for school classes with research tips and collaborative article improvement.

Lex – Danmarks Nationalleksikon is Denmark’s freely accessible, searchable national encyclopedia, with Danish-language factual content written by researchers and other professionals. Its collection contains more than 245,000 articles, including Den Store Danske, Trap Danmark, and other specialist reference works. Editors continually add material and revise existing articles. Trap Danmark covers subjects including geography, biology, archaeology, history, culture, architecture, and social and business life; its digital edition includes place descriptions, maps, images, and illustrations from public cultural and geographic databases. Lex provides definitions from Den Danske Ordbog within its articles. Readers can comment, suggest edits or new articles, and contribute images, though editors must approve proposals. Lex says articles may contain errors or omissions and invites correction suggestions. Institutions, public authorities, and businesses can license content through Tekst & Node. Text and data mining, including AI training, requires individual permission. Lex serves public education, including schools, universities, educational institutions, and libraries.
