This article argues that Harry Potter fan vids can be used in the classroom as works of secondary criticism about J. K. Rowling's primary text. It makes two claims: the first is that vids can be read as criticism of a particular text (in this case Harry Potter) alongside other critical essays on that text; the second is that the practice of doing so, for teachers of literature in general, and children's literature in particular, is a valid one. The article first provides readings of four vids, showing how each can be used to complement traditional scholarly sources as interpretations of the text; and then situates issues arising from the pedagogical possibilities of vids within the larger field of fandom studies.
