Fallout 3 skill books

General information
Reading a skill book permanently raises the corresponding skill by one point (two if you've taken the Comprehension perk). Most skillbooks are considered to have no owner even when present with someone's belongings (so they can be safely taken without loss of karma). Any that are considered to be owned will be noted below.

Types
Note that, depending on your gameplay choices, one copy of the following skill books may become unobtainable:
 * Big Book of Science and Lying, Congressional Style if you disarm the bomb during The Power of the Atom.
 * Nikola Tesla and You and Lying, Congressional Style if you detonate the bomb during The Power of the Atom.
 * Guns and Bullets if you do not pick the Lawbringer perk.
 * Lying, Congressional Style if you do not pick the Contract Killer perk.
