Once you mindread the goblin, you can read the book he thinks about in the bookcase on the other side of the room (from the entrance keep right and go to the end). This will remove a false wall, revealing a couple chests, once of which contains the soul forge contract you need to get the name. I think you have to go up to the next floor to get the key for the chest.
If you still want a guide, there is a
walkthrough and a
guide (with screenshots) available.
