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 South 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 West-Southwest 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 East of the entrance to the Flooded Metro). You will meet very little resistance, but if you want to get some good loot and XP for killing Raiders, you can pop into a major Raider camp which is easily recognizable from the route you are on. If you haven't "discovered" the Flooded Metro station, you can cross the paved road (North) to add that station to your map, then it's just a short walk down the paved road to the library.

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. (any of the five Music Paper books can be returned to Agatha however it can only be done once thus rendering the other four music books useless)
 * 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. If the special ink well and possibly the other supplies with it are taken after the Stealing Independence quest is completed it may result in not being able to load the Arlington Public Library Lobby (Xbox 360 version)
 * 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.

The Talon mercs usually number around 10 and have been seen to have a Sentry droid, various heavy weapons and misc small arms. Also they tend not to follow as much as usual.

Sunken River Boat
The Arlington Library is the nearest marked location to a partially sunken boat with some loot on board. Head east to the river round the southern side of the Arlington library. You will pass the Talon Merc camp entrance to your right. Keep east passing the unmarked entrance to "sewer" (which can be seen on your local map) and go to a small beach on the river.

Here I encountered 2 Mirelurks, a Mirelurk Hunter and a Mirelurk King. After dealing with these look into the river. North East there is a large boat half submerged, there is nothing on this. Almost directly to the East you can just see the roof of a small boat, swim to this to find:


 * Hunting rifle
 * Ammo Box (Very Easy) with 5 x .308 rounds and 13 x Shotgun Shells.
 * Ammo Box (Very Easy) with 5 x .308 rounds and 17 5.56mm rounds.
 * First Aid Box with a Bobby Pin, Dirty Water and a Stimpak.

Notable Loot

 * 10 Pre-War Books.
 * 3x - On the catwalk overlooking the main library
 * 1x - Beside the Public Terminal in the Media Archives
 * 1x - In the Media Archives area, in the room with two turret guns. Also the Ink Container can be found here.
 * 3x - In the Children's Wing, third floor (access through Media Archives)
 * 1x - Children's Wing, in the break room, on a table next to the Foodtronic 3000
 * 1x - Children's Wing, in the same room you'll find the Sheet Music Book in, on a desk.


 * Sheet Music Book - Found in the children's section of the library, the northwestern office room. Past the Firehose Box. Go right. Past the Nuka Cola Machine. In the first room you see enter. In the right cubicle by a music stand on the floor. This is the same room that you find a Pre-War Book in.
 * Ink Container in the 'Restoration Supplies' box in the Media section. It is a quest item and therefore cannot be removed after picking it up, but it will still occupy 1lb until you get the corresponding (sub-)quest from Button Gwinnett. If these 'Restoration Supplies' are taken after the Stealing Independence quest is completed it may result in not being able to load the Arlington Public Library Lobby (Xbox 360 version)
 * 5 Skill Books
 * Big Book of Science - Upstairs from the lobby to the right, through the hallway, on a desk in an office with two sofas. First door on thr right.
 * Guns and Bullets - Take the door from the Media Archive 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 - In the room where you download the archives, on the desk flanked by two sets of microfiche readers.
 * Lying, Congressional Style - Children's Wing, in the break room, next to the coffee-makers.
 * Tales of a Junktown Jerky Vendor - In the room with the pool table in the Media Archive, on the square table in the corner.


 * Nuka-Cola Quantum on a table in the SW corner of the room where you download the archives - as always, check the vending machines...
 * Holotags, Power Armor, Miniguns and other weapons looted from fallen Brotherhood of Steel soldiers.
 * 2x Stealth Boys - one on table in area overlooking the lobby; one in an ammo box in the lobby.
 * There is a safe (Average, requires 50 Lockpick) 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). The safe contains Prewar Money, Bottlecaps, and Scotch.  You then must drop though a hole in that room's floor to get out. (There may be a Stealth Boy in place of the Scotch on the 360 version.)


 * Just to the north of the main door there is a Pulowski Preservation Shelter that contains a Guns and Bullets.

Fast Travel from Arlington Library to Rivet City and JM resulted in 360 freezing.
