Ensuring high quality sources where needed, especially science/academic topics (narrow focus)
Fragment of a discussion from Talk:Task force/Wikipedia Quality
I think we should stat very clearly that printed peer-reviewed sources have priority over websites, even if they are not accessible for everybody. On the other hand, this of course invites problematic users to make up references of citing real articles for the info which is not contained over there. This behaviour is disruptive and should be labeled as such.
