Comprehension

Comprehension is a Fallout 2, Fallout Tactics, J.E. Sawyer's Fallout Role-Playing Game, Fallout 3, and Fallout: New Vegas perk.

Fallout 3
You gain one additional skill point whenever a skill book is read. However, points gained from books before selecting this perk are not doubled.

Fallout: New Vegas
You gain an additional skill point for reading a book (for a total of 4 instead of 3), and double the temporary skill points from magazines (for a total of 20 instead of 10). There are 52 skill books in New Vegas (64 if you have Dead Money and up to 72 with Honest Hearts if you are patient enough to reload many saves outside caves with a Workbench crate). As in all other instances of the Comprehension perk, it will not affect books and magazines read prior to selecting this perk.

J.E. Sawyer's Fallout Role-Playing Game
You pay much closer attention to details when you are reading. You gain 50% more skill points when reading skill-increasing books.
