The Encyclopedia of Earth
The Encyclopedia of Earth, from the Environmental Information Coalition and the National Council for Science and the Environment.
Following Wikipedia's model, The Encyclopedia of Earth (EoE) fills a specialized niche by focusing on environmental issues, particularly human interrelations with Earth's natural spheres. Unlike Wikipedia, contributors must apply and be approved by the online encyclopedia's editorial board before information may be added or modified; the editors offer a helpful discussion of the policy regarding Wikipedia content.
