I stumbled on Scholarpedia this afternoon while searching for computational neuroscience articles.
From the Scholarpedia main page, "The approach of Scholarpedia does not compete with, but rather complements that of Wikipedia: instead of covering a broad range of topics, Scholarpedia covers a few narrow fields, but does that exhaustively.
Currently, Scholarpedia hosts Encyclopedia of Computational Neuroscience, Encyclopedia of Dynamical Systems, Encyclopedia of Computational Intelligence and Encyclopedia of Astrophysics."
Authors include a slew of famous names, including Koch, Minsky, Damasio and Ramachandran. Indeed, the Scholarpedia isn't shy about telling you that amongst it's contributors are 12 Nobel Laureates and 4 Fields Medalists. All these in the computational neuroscience section alone.
Eventually editions of the encyclopedia will be made available in hard copy, as well as online where they will continue to be updated.
Amazing! Why haven't I seen this before?
