My catalogue of course support texts is available to Engl 383 students to be signed out from my office.
There is a useful on-line Comics Research Bibliography helpful for materials which can be ordered through Inter-Library Loans.
In addition to the salient research material the university catalogue, there is this online volume of Comics as Philosophy, edited by Jeff McLaughlin (requires SFU proxy authentication.)
There is also Graphic Storytelling by Will Eisner, and the Comic Book Encyclopedia : the Ultimate Guide to Characters, Graphic Novels, Writers, and Artists in the Comic Book Universe by Ron Goulart, both available at our Surrey campus Reserves section.
An online portal for G.N. web research is supported through an Association of College & Research Libraries at ALA.
