Strike, i love those trophy items. I been saying since 2238 they should be used by GMs to award players in special events.
This idea is not bad. I would consider supporting it (+1) if the boost you get from reading a book only applies to a single skill (random with each book) and not all of them simultaneously.
Mainly though, the addition of books is fun. I would love to see a few more:
"Pugilism Illustrated" for Close Combat
"The Grenadier" for throwing
"Tumblers Today" for Lockpick
"Big Bang" for Big Guns
"Sidlers Quarterly" for Sneak
"High Rollers" for Gambling
"Magnets Monthly" for Energy Weapons
"Lying Congressional Style" for Speech
...or some such. Preparing some additional images would likely be necessary.
With the addition of this many books, making any books less common would be done since each time you find a book (with the current rate) would spread out to more books. Thus it would take longer to find 10 Guns-n-Bullets magazines, but without increasing the grind as much as simply lowering rate to find any.
Also don't forget the "Technical Repair Manual" is in-game somewhere with its own image. Its about power armor but maybe could be used to increase any repair, like Oil (or even better than Oil).
Append: Oh! Don't forget there is already a "Chemistry Journals" book in-game. I think you get one on tanker quest. Not sure what that would boost.
