Encyclopedia of Arkansas vs Klexikon

Encyclopedia of Arkansas is a free web reference about Arkansas history and culture, with material for historians, teachers, students, and other readers. As of January 2026, it offered more than 8,200 entries and nearly 18,000 pieces of media. Readers can browse entries and media alphabetically, by category, county, or time period, and use County Explorer to explore Arkansas counties. A history calendar presents events associated with particular dates.

Alongside text entries and media galleries, the site provides lesson plans, student activities, quizzes, and history programs. It has an En Español section and continues to add photographs, maps, videos, quizzes, and lesson plans. Entries are reviewed and fact checked, with volunteer reviewers involved; public comments are moderated but are not fact-checked. Some sensitive images are blurred and carry content warnings. The project also invites people to suggest topics or media, write or review entries, and volunteer.

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.
