If you gave the spice amulet to its rightful owner in Spicing Things Up, you have three options:
1) Give two (or more) books to the Golden Hand to get +1 rep to access the Library. This will lower your rep with the Royal Loreseekers, but not by much.
2) Fight your way into the library, becoming an enemy of the Golden Hand.
3) Just ignore all things library related (including the quest Lost in a Good Book).
Alternatively, you can (or could have) given the spice amulet to the Golden Hand, and all the books to the Royal Loreseekers. This gives you +1 rep with the Hand, which is just enough to get into the library. You'll take a small reputation hit in New Garland and really irk off the rightful owner of the amulet.
Most players just say heck with it and fight the way into the library. Of course this was before the Golden Hand sold anything to the player.
