Fallout: New Vegas skill books

General information
Reading a skill book permanently raises the corresponding skill by three points (four points with the Comprehension perk). Most skill books are identical to the books from Fallout 3, with the exception of Wasteland Survival Guide, which attributes to the newly added Survival skill, and U.S. Army: 30 Handy Flamethrower Recipes, which was removed because the "Big Guns" skill was merged with "Small Guns" into the new skill "Guns".

Dead Money adds an additional copy to each skill book type, with the exception of Wasteland Survival Guide.

Honest Hearts introduces the Workbench crate, a container with random loot that has a chance of containing various skill books.

Old World Blues adds two copies of ''Chinese Army: Spec Ops. Training Manual and a copy of Big Book of Science'', in addition to a new mechanic enabling the player to create a single copy of each book at a workbench, using 25 blank books, two tubes of wonderglue and the appropriate recipe.

Lonesome Road contains additional skills books as well, however not all have been noted yet. If you wish to see the locations of the skill books that have been noted see Lonesome Road Skill Book Locations
