In FO3 pre-war books are in a limited number, therefore preventing the player from exploiting the quest.
Except in New Vegas they are abundant!
Try this.
Go to Airlington Library and pick up the two guaranteed stealth boys there.
Travel to Rivet City and if you already don't have a good weapon, like an Assault Rifle or need EC cells for you laser/plasma pistol, buy or steal one there.
Use Anacrocia station to reach the Museum and then use one stealth boy to reach Judiciary Metro (or if you are suicidal/brave enough, go fight the super mutants along the way to the station).
From there you need to enter Union Station, a plasma pistol or assault rifle + 1 psycho + 1 med-x make the fight very doable, you just need to have ammo (that's why you've stopped at Rivet City, not because of the bobblehead
Make short order of the mutants there, start the reactor, travel to New Vegas and loot, loot and loot Dr. Mitchell house, Nellis school, Pearl and Loyal houses for the books. Did I mention if you want to go overkill you can also go to Camp Golf and Jacobstown and loot, loot and loot more? Mormom Fort is another excelent target, as well the Abandoned BoS Bunker.
Return to the Union Station and travel to Airlington Library.
Enjoy your 10.000 caps at level 3 or 4 and the ton of XP she will give you, advancing you at least to the next level, if not more.
Shouldn't this quest be rebalanced? At least not giving the player the XP or lowering the ammount of caps for the books? Or restricting the books she accept from the ones you find in DC?
Just a suggestion, nothing more than this.
