Arlington Library

 is a mostly-intact Public Library building in Fallout 3. It is now occupied by Raiders. is easily found by following the Potomac river SE past the Citadel, then turning W to follow the road just South of the Citdael. It is directly across from Alexandria Arms and about two miles NW of the Jefferson Memorial.

Moira Brown will ask you to explore the library and download the card catalog and the library's full archives to disk as part of The Wasteland Survival Guide quest. There is also one of five Music Paper books inside that can be returned to Agatha as part of the Agatha's Song quest. Additionally, there is a special ink well inside that can be used to forge a duplicate Declaration of Independence as part of the Stealing Independence quest.

When you enter the Library you will be forced to speak with Scribe Yearling, a Capital Wasteland Brotherhood of Steel agent who is tasked with archiving all pre-war knowledge into the Brotherhood's central computers. If you do not insult her she will offer to pay you 100 Bottle caps and 10 XP per Pre-War Book given to her. She will also give you access to the Library's computer terminal, where you will be able to download the card catalog to complete Moira's quest. To complete the optional objective, you will have to explore further into the building until you find the Library's mainframe computer buried deep within a raider den. Three Brotherhood of Steel soldiers from Scribe Yearling's detachment will help you clear out the building.
