We noted last month the Cornell wiki that required that experts be validated.
Today's Register has a venture that builds beyond similar scepticism about the reliability of an encyclopaedia on which anyone can post.
The Register notes:
The project has a long list of institutions signed up, including the National Council for Science and the Environment, the American Museum of Natural History, the World Resources Institute, the UN and UCB.
Material will be available for free, but the project's FAQ says that for a small premium, copyright material will be available to subscribers. It also offers a richer, and a much more attractive user interface.
