Scribe Yearling

ScribeYearling
This Scribe can be found in the Arlington Library. She is related to the The Wasteland Survival Guide quest. Also when speaking with her upon entering the building for the first time, if she is spoken to nicely she will offer you 10 XP and 100 caps for each Pre-War Book you take to her. 10 books are in the building she is in and many others are scattered through the wasteland.

Bugs
It has been known for her to just disappear and not be found again. Note that she will move about the building to some degree. I've seen her sitting at the counter upstairs and wandering the corridors.
