The term Canon, from the Greek word κανών (Kanon), meaning "reed" or "measuring rod", has multiple definitions in the literary world, the most common of which are specified as Literary Canon, Canon Fiction, and Biblical Canon (Landow). A work that belongs to a canon is guaranteed to display quality, status, and aesthetic appeal (Landow). Once the work is entered into a canon, it becomes "canonized" (WiseGEEK).
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).
In religious terms, Biblical Canon is a list of valid and recognized scriptures (Slick). Each type of religion has their own form of a canon (Slick). Often, canons are used in reference to books of the Bible that are officially recognized by The Church (Keathley). While in a different religion like Judaism, the canon only consists of books of the Old Testament (Slick).
