Obtaining the skill

In the briefing it said to give the book to Aranwen. But in the Additional information, it said to talk to Aranwen, should this be changed? I was unsure what to do so I asked around because I didn't want to loose the book accidentally. I'm not sure about testing the Giving method either....

If it can cause confusion, yes, the sentence should be clarified. In this case, though, the "give the book to Aranwen" is straight out of the quest info, so that shouldn't be changed, but instead a note should be made in the same section explaining what to really do.

I'm fairly sure that completing the quest is all that's necessary though.

Ehh it sounds like you have an older quest of AR. older quests (That 2x2 scroll o.e....oh yeah that thing) made it so that you have to talk to her, then talk to her again after completion of the AR book. Unless it was updated to that old quest, then yes, it should be changed to match. Anyways, you must have the book in your inventory when all 10 pages are in it. After that, just talk to her and that part of the quest will be complete.
