Lex – Danmarks Nationalleksikon vs Wikipedia

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.

Wikipedia is a free encyclopedia available on the web and through mobile apps, with editions in hundreds of languages, including editions with over one million articles. Volunteer editors create and revise content, check facts, cite sources, discuss entries, and moderate the encyclopedia. The Wikimedia Foundation hosts and protects Wikipedia, while editorial decisions are made by volunteers. The Foundation says the service is available without advertising or paywalls and is funded mainly by donations, not advertising, subscriptions, or sales of users’ personal data. The official Android app supports searching articles, changing languages, saving reading lists for offline use, and adjusting themes and text size. Its listing says the app has no ads, does not track or collect data, and encrypts data in transit. MediaWiki provides a REST API for interacting with installations including Wikipedia. The Foundation publishes a privacy policy, says it prioritizes speed, reliability, and availability during traffic spikes, and publishes transparency reports twice a year. Its financial statements are independently audited annually. Wikipedia is free at free.
