I missed this:
Characters can also "Aid Another" with checks done through research (see below), but in this case, they must do research of their own using the same time and resource level as those employed in the main check. In most cases, this means simply accompanying the skill user to the same library and helping them by checking other books while they read.
So my question is half answered. Yes, sort of. While I can appreciate how well-thought out this all is (and I may use parts of it), the problem is that is very time consuming. One PC spends 1d4 days doing research while the rest of the party does what? I hate splitting up the party and frankly they'd be better off asking an NPC librarian to do the research for a fee of course.
