Canon
The term Canon has multiple definitions in the literary world, the most common of which are specified as Literary Canon, Canon Fiction, and Biblical Canon (Landow).
Literary Canon
The term Literary Canon generally refers to a work or works of fiction that are widely respected by critics or scholars or are considered important to a genre, period, or study of literature. It can also refer to the popular works from a period, regardless of scholastic value (WiseGEEK).
Canon Fiction
Canon Fiction refers to works that fit into an author's 'official' (or widely recognized) continuity (Landow). A good example of this is the Sherlock Holmes Canon.
Biblical Canon
