This study examines whether canonical literature exhibits consistent structural signatures in networks of textual similarity across languages. Using four diachronic corpora of prose fiction (5,000 texts, 17th–21st century), we construct time sensitive similarity networks, with edges weighted by textual proximity. Canonical status—derived from multiple markers of canonization—is analyzed in relation to various centrality measures. We find that global metrics such as betweenness and degree centrality show limited association with canonization, while sub-cluster centrality offers a more reliable signal. Our analysis also reveals temporal shifts: in some periods, canonical status aligns with structural centrality, while in others the correlation weakens or even reverses, with canonization favoring more distinctive or peripheral works.
