Sorry, I neglected to list the DC/Malibu crossover, which
is on the DVD. I've amended the list accordingly. Basically the only things it doesn't have (reprints aside) are the Trek/X-Men crossovers, the newspaper strips, and the TokyoPop and IDW stuff that's still in print.
There's a lot here I've never read: Most of the Gold Keys, all the Power Records, many of the Malibus, most of the '90 Marvels, about half the Wildstorms. And even more that I have read but no longer own.
