I just found this on uesp:
Redoran Style Master is awarded for learning all of the Redoran Style motifs. There are 14 books in all to find. They can be found in "owned containers", Thieves Troves, and people's pockets in Vvardenfell. Those who don't have access to the Morrowind DLC can still find them in Guild Stores.
I thought you could only get them from pickpocketing, so why does this say you can get them from containers within trespass homes? Or am I misunderstanding the meaning of owned containers?
