Assume that the future can change based on your actions, so any historical information that you bring along with you from the intervening 25 years may quickly drift out of the new realities history.
Edit: also assume that you can be given a healthy 21-year-old body if you want or take your previous self’s place.
Further, identification will be provided for you if you were not born at that time.
That’s why most of the stuff is technical or scientific information for the researchers; things that aren’t subject to change, just technical info. The money stuff I would hope to manage in less than 6 months from my arrival, because even in that short time I’d expect a lot to change by the end of it.
It’d just be a question of getting that initial funding off the ground with which to set up my research institution. After that, the few things I don’t release for free should cover expenses.
Sidenote since I didn’t address it in the original reply, taking over the world is impractical even with future knowledge, but as the person in charge of this outfit that would quickly be the world’s most advanced research tank, I’d probably have a lot of influence, which is the best anyone can practically hope for, I imagine. A lot more than the last 25 years of advancement would be needed to actually take over I figure.
