There are tons of books and manuscripts in this game. As a player that likes to steal/pick up everything including the kitchen sink I have a question. Is there any use in snagging all of these non-alt highlighted items? Right now I have a chest full of junk, but if I could sell it latter in the game I would gladly keep it.

Also, is there any use in the "magic carpet", or the drugs that you get earlier in the game, or should I just ditch those?
