Just finished our first game, and this was a standout card in my deck. Daisy Walker gets a free action to use tomes, so this is a free card draw every turn (doubling your basic rate of drawing) and it's filtered, meaning you won't ever draw a Weakness at the wrong moment on your turn. Plus, of course, it turns on her ability.
A fringe benefit is that it gives a shuffle (not sure how useful this will ultimately be, but gives a nice combo with cards like scrying to shuffle your deck if you don't like 2 of the 3 you see), and also note that it isn't unique. Sure, I can't often see having two, as there are likely more crucial tomes to take (especially over time as we get new cards), but extra card draw for your colleague could be nice.
I mean... what's not to love? I can't ever see Daisy not running 2 of these, and in fact I'm going to be packing Research Librarian as a two of to get it to my hand as quick as possible.
