Yearning for Learning

Yearning for Learning is an unmarked and repeatable quest in Fallout 3, given by Scribe Yearling at Arlington Library.

Detailed walkthrough
Scribe Yearling is searching Arlington Library for books and asks the Lone Wanderer to help. So long as she is not insulted, Scribe Yearling will offer to pay 100 caps and 10 XP per every pre-War book given to her.

Bugs

 * Sometimes, Scribe Yearling will ask you how your search for the books is going, and when you are given the dialogue choices with her, you will not be able to give her your pre-War books.
 * PC users may be able to work around this bug by selecting Scribe Yearling in the console and typing.
 * The easiest way to fix this is to create a text file in the Fallout 3 directory. The easiest name is books—real file name will be books.txt then paste the following in the file and save it:

In the game, go to the library and stand near Scribe Yearling. Open the console and type: bat books. This will trigger the conversation. Leaving out Primary ID results in a missing target error, but the original code was correct.
 * Carrying more than 99 pre-War books and telling Scribe Yearling "just take all the books I have" will cause her to take only 99 books, yet give you caps and XP for all the books you carry. For example, carrying all 102 pre-War books and giving them all to the scribe gives you 1020 XP and 10200 caps, yet leaves 3 books in your inventory.
