Enciclopèdia.cat vs Klexikon

Enciclopèdia.cat is a free Catalan-language reference portal covering subjects such as language, history, economics, art, politics, geography, science, and nature. It lists 45 reference works and more than 800,000 articles, spanning dictionaries, general and specialist encyclopedias, thematic works, atlases, chronologies, statistics, and yearbooks. Search one or more words across the portal or within a selected work, then order results using factors such as title, work, and frequency. Readers can also explore the Gran Enciclopèdia Catalana through a topic-based knowledge tree. Its digital edition has more than 360,000 articles and 100,000 illustrations, along with some audio and video. Specialist titles include references to sports and music and a cinema dictionary. The portal provides citation tools and educator resources, with text and images and continuously updated content. Registration adds access to +Enciclopèdia content, editor chat, and tools to sort and filter search results. The service is available on the web, not as a mobile app; the publisher suggests a home-screen shortcut as an alternative. Support is available by phone at 934 126 124 and by email at [email protected].

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.
