Sure, here are some links:

Kahlenberg and Arcidiacono initial and rebuttal reports linked here: https://studentsforfairadmissions.org/sffa-files-motion-for-summary-judgment-against-harvard/
In that second cite are also links to Harvard’s own internal OIR analyses (3 of them, right near the bottom of the page), which are very interesting.
Last, the Trump DOJ just today filed a brief in opposition to Harvard’s motion for summary judgment. The excerpts from the depositions of Fitzsimmons and other adcoms are particularly interesting and I don’t think we have seen those before today. My opinion is that this will go to trial (Harvard will fail in its motion to dismiss) and that Fitzsimmons will lose his job after 45 years at Harvard.
