If you can't google it, then I doubt they exist. The other place I would check is a library - they'll have something like that and might know where you can get it from.
Given that a database like that is going to be millions of records that are constantly updated, it's almost certain to be proprietry (I would expect a bunch of different variations, ideally a licensed feed - xml if you're really lucky). I would be surprised if it were cheap. And if it is cheap, I'd be surprised if it were good.
