This principle of grouping has led to more specific uses of the word in different contexts, such as the Biblical canon (which a particular religious community regards as authoritative) and thence to literary canons (of a particular "body of literature in a particular language, or from a particular culture, period, genre").4
W.C Sayers (1915–1916) established a system of canons of library classification.5
S. R. Ranganathan developed a theory of facet analysis, which he presented as a detailed series of 46 canons, 13 postulates and 22 principles.6
There is also the concept of the canons of rhetoric, including five key principles that, when grouped together, are the principles set for giving speeches.7
