Clever boy :p You will probably find use to those books in their respective areas. I suggest having Aredhel slowly browse those books in his travels.
Even if those books don't hold any info useful to the quest, they will definitely sell for more to a collector in a properly established city, rather than shady thieves in Soglash!
Now, I have a confession to make: I haven't been tracking any of your starter gold.

So, I propose one of three things to bridge this issue!
First, you could all let me know how much dollars you have saved from the start, and i can record this and keep track from here-on in.
Second, I can allocate 50 starter gold to all of you, having you all on an even level wealth-wise, and I can keep track of it from there.
Finally, we can pool gold and loot, and rather than each of you individually tracking how much you all have, you can have a single well to draw out of, so to speak which I can keep track of. This way, you will start with 200g in your 'starter pool' and people can share all of the loot. Whenever a new character joins in the game, an additional 50 'starter gold' will be added to the pool.
talk it out and let me know what you would all like; i'm happy for any of them to happen!
