NOTE: YouTube is a classic example of one of the strengths and weaknesses of the Internet, which is the fact that anyone can post videos. As such, the quality and scholarly acceptability of videos varies greatly. There may be useful video clips on YouTube, however, so it is worth a look. Before referencing any material from YouTube (or other video sites on the Internet) in a paper or using a clip in a presentation, though, it is highly advisable to check with your instructor concerning the acceptability of the video for the assignment.
