EARTH

This is pretty cool. The Encyclopedia of Earth wants to be the largest reliable source on environmental issues. It is free, online, and sort of a controlled Wiki. Approved authors can change each others' work but there are assigned editors, and nothing is done anonymously.

They borrow (with permission) articles from government agencies and other reliable sources. So, for example, the article on Rachel Carson comes from the US Fish and Wildlife Service (her former employer) but there is a separate article on her environmental ethics written for the Encyclopedia by a philosophy professor in Colorado. (There is a brief bio of each author, so you can judge their reliability.) This is followed by a dozen other articles that mention Carson.

Very nice work. We could use a hundred more in different fields.
