It's not exactly a new article, but I realized that my article "Un-Defining 'Comics'" from the International Journal of Comic Art way back in 2005 was not downloadable from my site. That is now fixed! A downloadable pdf of the article is now available.
This article was among my first published works on visual language (and it kind of shows...gulp), and is the first that argues for a separation between the idea of "comics" and a "visual language" made up of images (i.e. "comics ≠ sequential images"). Enjoy!
