Yearning for Learning

 refers to an unmarked and repeatable quest in Fallout 3, given by Scribe Yearling at Arlington Library.

Repeatable Quest

 * If you do not insult her she will offer to pay 100 caps and 10 XP per Pre-War Book given to her.
 * Books that can be turned in have a value of 1, a green cover, and show a special "Book" icon.
 * There are some pre-war books which aren't accepted by Scribe Yearling. These pre-war books have a value of 5, a blue cover and appear with the "Junk" icon in the inventory.

Bugs

 * Sometimes, Scribe Yearling will ask you how your search for the books are going, and when you are given the dialogue choices with her, you will not be able to give her your pre-war books.
 * Sometimes, Scribe Yearling will disappear from the library and won't be able to be found, it is unknown how to reverse this and may only be in the Xbox 360 and PC version of the game.
