This quest only boosts a single library (the one in your best science city). I can't remember the exact wording of the in game messages, but I think that is how it is supposed to work.
Admittedly it is a very feeble reward - the extra scientist from the great library is the only decent one from that quest.
Only in one; it works as intendedClassic Literature

Genv FP said:It boosts every library.
Not unless the change was sneaked in during the most recent patch. It's one library only.
The quest consisted of building 9 libraries, so I had 9 of them at the moment and the option stated that I would get +2in each library.
And yes, quests like these affect future buildings. I had a +2bonus in every barracks last game and it included those I build after the quest.
The extra scientist attached to the GL doesn't expire when the GL does.Anyway, I think the +beakers in every library is a better option that an extra GS attached to an expiring wonder.
I got the horse whispering quest, completed it, and chose +1per stable. All 7 current stables got it, but some new ones did as well, while others didn't. I believe (have no proof) that only stables I built before the the expiration (entering Renaissance) got the bonus, while stables built afterwords didn't.
