Have you noticed that the “How cited” page for cases on Google Scholar now estimates how much the citing reference talks about the case? Think of it like the “depth of treatment” rating in Westlaw and WestlawNext, or a bit like “analysis” descriptions in Lexis and Advance.
Levels are: “discuss at length,” “discuss,” or “discuss briefly.” (It seems that no icon means that the earlier case was merely cited in a parenthetical or string citation.) Nifty. And free!
