I don't know if the SetQuestItem command works in this game, but if it does, setting the Flag to 0 will allow you to drop the item or put into a container..
SetQuestObject 0
However, if that does not work, then just drop the item using the remove command. Just note, it is gone from the game world once you do this. Note, since these books are part of a DLC, you need the offset value (load order number of the DLC) when using the Item ID.
Also, for Quest Related weapons, you can equip the item, then use a Weapon Rack to display it. Then it is removed from your inventory. I have not tried to pick something up again to see if it gets stuck, so beware of that.
