First off. I want to figure this out myself. So please dont respond with a solution.

Im trying to get the book "working with stock", I have absolutely NO idea as to how and where. But Harnquist seems like a good start.
The following conversation is probably very funny if you know how to get the book. (I dont)
Me : Hello
Harnquist : Greetings traveller. Quality arms and armor you'll find at my shop. Can I help you?
Me : give me the book
Harnquist : Books are very entertaining... especially the magical books with the moving illuminations, don't you agree?
Me : yes
Harnquist : Sorry, can you use a simpler but complete phrase?
(Personal note : when NPC's ask a question, yes and no should be valid responses)
Me : hmm, no (I cant make it any simpler than "yes")
Harnquist : Sorry, can you use a simpler but complete phrase?
Me : working with stock
Harnquist : Sorry, can you use a simpler but complete phrase?
Me : aaarrrggggghhhh
Harnquist : Sorry, can you use a simpler but complete phrase?
Me : give me working with stock
Harnquist : You're going to have to be more specific than that
Me : give me the book working with stock
Harnquist : Maybe try the library? Books can be found in many places.
Me takes Harnquist out back and kills him.
So, the library eh?? Off I went.
Jayose : Welcome to Jayose's Librams and Codexes. I hope your visit is an enlightning one.
Me : give me the book working with stock
Jayose : If you're looking to borrow a book. I'm afraid i cannot allow you to do that at this time. But you may certainly read them here. Please enjoy.
Me commits suicide right there in the library.
My question is. How did anybody get anywhere in this game??? I have the same problem with ALL the quests I have tried, and it's just not funny. I could do the obvious thing, and ask somebody ingame, we could even roleplay it. But there MUST be a way to figure this out ON YOUR OWN, but right now, I don't see it.
Like the quest "Harnquist needs tin"... do you really expect me to find this on my own?? I found iron, but only because I noticed other people digging, and I haven't seen anybody dig anywhere else.
