For a paper I'm writing I need to use (as a blackbox) the following theorem: if there is a proper class of Woodin cardinals and $G$ is set-generic, then $L(\mathbb{R})$ and $L(\mathbb{R})^{V[G]}$ are elementarily equivalent. I have seen this result quoted in a number of places, but I can't seem to track down a reference. What is a good source to cite for this?
More generally, is there a single source where the basic generic absoluteness results are presented together? I'm not interested (at the moment) in consistency strengths but rather outright implications, if only because those are snappier to state for broader audiecnes.
