Lex – Danmarks Nationalleksikon review
A broad, free Danish reference platform with search, multimedia, citations and quizzes.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
Lex – Danmarks Nationalleksikon is a free, Danish-language online encyclopedia operated by Foreningen lex.dk. It brings together Lex and multiple reference works, including Den Store Danske, Trap Danmark, biographical encyclopedias, historical resources and specialist works. With more than 245,000 articles written by researchers and other subject specialists, it is aimed at public information as well as schools, universities, educational institutions and libraries. The strongest fit is for readers who want broad Danish reference coverage in one public web destination.
Search is a central strength. Users can search across multiple reference works, see full-text results across articles and receive recommended article suggestions while typing. Articles can include images, maps and illustrations, while interactive quizzes add a more engaging way to explore topics. Built-in citation text supports readers who need to reference an article in school, university or library work. These features make Lex more useful than a basic article lookup site, particularly when research spans several types of reference material.
The platform also supports ongoing participation: registered users can comment on articles and suggest changes, while the published update model is continuous. Its scope is intentionally focused rather than general-purpose, with Danish-language coverage at the center and web access as the supported platform. Choose Lex for free, wide-ranging Danish reference research, cross-work discovery and citation support. Readers seeking a multilingual reference service or a broader platform mix should look elsewhere.
