Brockhaus vs Klexikon

Brockhaus provides online reference works, courses, student training, and digital teaching materials for private customers, schools, and libraries. Its online encyclopedia offers expert-reviewed information across subject areas and is regularly updated. The School Lexicon supports secondary students doing research and preparing presentations or coursework, while the Children’s Lexicon presents child-oriented content through clickable graphics, images, video, and audio. A reading aid can read text aloud and translate articles into more than 60 languages. Brockhaus says subject experts and trained educators create its reference and course materials, which an independent editorial team checks. The service works on internet-connected digital devices. The company states that its servers are hosted in the EU and that it uses SSL encryption for data sent through its websites. The Children’s Lexicon is described as ad-free, without external links, and GDPR-compliant. Individual plans have a 14-day free trial. Adult encyclopedia plans cost €6.99 a month or €69.99 a year; teen and child plans cost €8.99 a month or €89.99 a year.

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.
