The Canon of Consistence, as defined by CCC, is the principle stating that:

(A). Catalog code rules should ensure consistency between all added entries of a document and its main entry.

(B). To introduce complexity in the style of writing for different entries.

(C). Entries of all documents must exhibit consistency with each other in essential aspects such as choice, rendering, style of writing, heading, and other sections.

(D). To discourage readers from becoming familiar with the catalog.
