For as long as I have been aware of Wikipedia, I have been telling students not to use it as a reference, mainly because as researchers we do not know who has written the information. I have generally told students to use the references at the bottom of the page. Sometimes if it is a new concept I will say, read the Wikipedia definition to understand the concept and then find a better reference.
After reading the information in the chapter “New Models of Information Production” (Saulles,2012) about the comparison between Wikipedia and Encyclopedia Britannica’s science-based entries which concluded that there was little to choose from between them in terms of accuracy, my opinion of Wikipedia is not so clear cut. There is still a lot of merit in finding the original source with a named author. Maybe though Wikipedia is not as bad as I am making it out to be, as Berinstein(2006) said ...the kid’s alright and so is the old man (Britannica.)
