Hi.
I'm looking for encyclopedias under a free license, and open to edit to the
general public (may require registration) with a very board scope, like
Wikipedia, or encompassing in its scope a wide area of hard science and the
related engineering fields (for instance: electrical engineering, physics or
mathematics).
In English, I know of Citizendium. In Spanish, there was the Enciclopedia
Libre Universal (Universal Free Encyclopedia), but it is down currently.
What other projects like this exist?.
Regards.
