The 500 pages per month rule may have made sense back when everything was actually on paper. But these days, just one DVD or flash drive could hold all 329,000 pages. I'm guessing that it's actually more work for them to split the release into 500-page segments than it would be to release them all at once, so I'm inclined to assume they're intentionally going at the slowest allowed rate because there's information in there that they'd rather keep to themselves forever.
