A few years back, we discussed Henry Jenkins "Textual Poachers," which was an academic treatise on ... fanfiction. Unfortunately, the book was published before
Lois & Clark, but he does use examples from
Beauty & the Beast. If you're interested in a sympathetic view of fanfiction, you can find out more at
Textual Poachers and other links .
It would be nice to see a more up-to-date discussion from Arpe, particularly since it looks like she thinks L&C should be included.
