WRS -- Encyclopedia of Earth

The Encyclopedia of Earth is an open-access encyclopedia of topics in the biological and earth sciences, with articles written by reliable professionals in their fields, but aimed at a non-technical audience. The Encyclopedia is free and fully searchable.

The homepage includes a featured article, as well as a biography on a featured contributor, country profile, featured ecosystem, and a featured "classic" paper in environmentalism. The content can be browsed as well as searched by title of article, author, or topic.

The Encyclopedia also offers RSS feeds which alert users to new articles, new featured articles, and new revisions of older articles.
