I notice that there are a lot of novel, beside Toaru Majutsu no index and Shinyaku Toaru Majutsu no index that are the "main novels" which novels are canon in the Other Literary Works section (That include the specials, the Toaru Majutsu no index SS and the Toaru Kagaku no Railgun SS)?
And beside the novels which mangas are canon?
The 4-Koma series are canon and the Anthology manga are canon?
And which Special Stories are canon beside The Miracle of Endymion?
Sorry for my english but i have many questions.
