Fallout: New Vegas skill books

Overview
Skill books are special items which increase the player character's skills when used. Unlike those of skill magazines, the effects of skill books are permanent: reading a skill book permanently raises the particular skill by three points (four points with the Comprehension perk). Books are one-use items: they are removed from inventory after use.

Most skill books are identical to the books from Fallout 3. Exceptions are the Wasteland Survival Guide (which improves the added Survival skill) and the U.S. Army: 30 Handy Flamethrower Recipes (removed because the "Big Guns" skill was merged with "Small Guns" into "Guns").

Fallout: New Vegas has a total of 52 skill books, with additional 46 copies added by add-ons:
 * Dead Money adds an additional copy of skill book, except for the 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 the Chinese Army: Spec Ops. Training Manual and one of the Big Book of Science. Books are also able to be crafted once at a workbench, using 25 blank books, two tubes of wonderglue, and the appropriate recipe.
 * Lonesome Road adds a single copy of each skill book.

The total amount of skill points earned from reading every obtainable skill book (excluding those found as random loot in Honest Hearts), the player character can gain the equivalent of 282 skill points (376 with the Comprehension perk).
