Pre-War book (Fallout: New Vegas)

A fairly rare item. Desired by the Capital Wasteland Brotherhood of Steel.

Several can be found in Minefield, inside the houses on various bookshelves and tables. There are also some in RoboCo.

One of their Scribes, located within the Arlington Library, will reward you with 100 bottle caps per book for contributing these to their archives.

Bug
A possible bug as of v. 1.0.0.15: the Pre-War Books bought from merchants can not be turned in for caps at the Arlington Library. It's easy to tell the difference: books that can be turned in are Value 1 and show a special "Book" icon, while books that cannot are Value 5 and appear with the "Junk" icon in the inventory.
