This question gets asked a lot. We librarians have criteria for evaluating a resource: reliability (Wikipedia is always there), authoritativeness (check out the recent study published a few months back in Nature), depth (1 million plus articles and growing daily) and specificity.
this last one is key. It measures how much a resource know sits audience, and how well the contributers provide that need. It’s a gage of how much passion the contributors have for their subject. So, how specific is Wikipedia?
Today I found this article: Gorillas in Silver Age Comics.
Itâ€™s that specific.
