Deletion of List of civilisations in the Culture series

Comment: there are some fairly detailed articles on The Culture in the encyclopaedia, and this is an extension of those. As it stands, the information is too detailed to fit easily into another Culture article. What bothers me is that it seems overly detailed and somewhat light on references. Possibly more of a problem: it smacks of the dreaded |original research - it's an impressive collection of information about these civilizations and it is certainly of value, yet Wikipedia's own policies discourage this sort of article. On balance though I think it should stay
Stance: keep
