What is the significance of “G-canon” and “C-canon” notations?
According to official reports, the “Holocron” uses four classification symbols to annotate STAR WARS sources. “G” sources are claimed to have some contribution from George Lucas. “C” denotes ordinary continuity (official sources). “S” denotes secondary continuity: tales where the events are discontinuous but characters or other entities may exist somewhere in the STAR WARS universe. “N” denotes non-continuity sources, such as the “Infinities” comics. “S” and “N” classifications are a helpful guide to treating the lowest sources in the STAR WARS literature. The distinction between “G” and “C” does not absolutely settle the objective evaluation of continuity. These two classifications don’t coincide with the boundary between canon and EU. Not all “G” sources are canon (e.g. prologue by George Lucas in the paperback edition of the EU novel Shatterpoint). All canon sources include contributions from at least a few people other than Lucas. Many sources originate in a mixture of “G” and “C”
