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 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.

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.

Notable Loot

 * (at least)10x Pre-War Books. [Loot could possibly vary randomly. I picked up every book in the building and only got 8: 1 in the room with two turret guns, 3 in the Children's Wing room on the third floor, 2 on the catwalk overlooking the main library (1 more on a table opposite side as the prior 2), 1 in the booby-trapped room.] There is another in front of the rear-most Nuka-Cola machine in the alcove of the Children's Wing, before the last raider room, and one sitting on a desk at the northernmost entrance to the Main Lobby second-floor catwalk, one may also possibly appear beside the Public Terminal in the Media Archives.
 * 1x Sheet Music Book - in the classroom atop a children's school desk immediately to the right as you enter the room. An alternative location is in children's area on the first floor within a small office area that has a metal music stand in it.
 * 1x Ink Container in the 'Restoration Supplies' box in the Media section. do not pick up prior to speaking to Button Gwinnett as it will jam 1 weight permanently.(No, quest items before you clear the quests don't really has their weight.) You will also find a Pre-War Book in this room as soon as you cross over the wooden planks along the right wall, before walking over to the 'Restoration Supplies' box. On the opposite side of the room is another wooden plank ramp you can cross to reach a table with 3 frag grenades.
 * 5x Skill Books - Big Book of Science (from lobby, up one flight of stairs on the right, in an office). Guns and Bullets (from the Media Archive, take the Southern door to the Children's Wing). You'll also find 3 of the above mentioned Pre-War books here, along with a shotgun and some ammo. Tumblers Today (on a desk in the room where you download the archives), it's on desk flanked by two sets of microfiche readers in the room with the safe (it's the southern-most room) that is very close to the Children's Wing door. . Lying, Congressional Style (Children's Wing, it's on a shelf in a break room) On the closest of the 2 tables in that same break room is a Pre-War Book. There is a copy of Tales of a Junktown Jerky Vendor, which can be found in the room with the pool table in the Media Archive.
 * Nuka-Cola Quantum - on the SW corner of the room where you download the archives.


 * At least 2x Holotags from fallen Brotherhood Of Steel guys.
 * 2x Stealth Boys - one on table in area overlooking the lobby; one in an ammo box in the lobby.
 * There is a safe in a doorless room which can only be entered by dropping through a hole in the floor in the Children's Wing on the top floor (which is only one room), then you have to drop though a hole in that room's floor to get out.
 * Just to the north of the main door there is a Pulowski Preservation Shelter that contains a Guns and Bullets.


 * There is a Nikola Tesla and You at Talon Company outpost to the south of the library
