Arlington Library

 is a mostly-intact Public Library building in Fallout 3. It is now occupied by Raiders.

Location
is easily found by following the Potomac river SE past the Citadel, then turning West to follow the road just South of the Citadel. It is directly across from Alexandria Arms and about two miles NW of the Jefferson Memorial.

Another route to the library is to go far south from Megaton, as far as you can go, then head east, hugging the bottom border until you are almost to the library (past or south of the entrance to the Flooded Metro). Watch out for a Talon well off to the right as you approach the library. A sniper round or two will take him out without risk, or you should be able to sneak along the paved road at this point to get into the library without conflict.

Quests

 * 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.
 * Yearning for Learning: Scribe Pre-War Books: If you do not insult Scribe Yearling she will offer to pay you 100 Bottle caps and 10 XP per Pre-War Book given to her.

Inside
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. She will 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. A couple of Brotherhood of Steel soldiers from Scribe Yearling's detachment will help you clear out the building, two in the Main Lobby, two in the Children's Wing and two in the Media Archives, if the ones from one section survive, they will help you clear out the other areas as well.

Talon Company Outpost
There is a Talon Company outpost south of the library. One of the mercs patrol just south of the library.
 * The camp has a Nikola Tesla and You on the topmost level, on a round table.
