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.
