Profs expect students to march into the library and acquaint themselves with the subject’s/discipline’s fiefdom. If not, then the student is lazy and lacks the necessary drive or will. The Natives don’t expect to have to navigate fiefdoms. For them, at least thus far, knowledge and data have been without borders. It does not occur to them that there would be a specific database for articles about Colonial literature that is not accessible through a quick key-word search from their dorm.
It can be useful though. If we start talking to our students right away about the relative value of websites.
Of course, I don’t hate Wikipedia. (Unlike most faculty.) I’ve seen it do some good things.
