This is the preface to *Oceanic Mythology* (1916) by Roland B. Dixon of Harvard University, a comparative mythology survey belonging to the scholarly tradition of early 20th-century anthropological folklore studies. Dixon's work compiles and synthesizes published myths from across Oceania — covering the Pacific island regions — into a single volume, something he identifies as a gap in the existing literature. The book retells myths in paraphrased form rather than verbatim transcription, with original sources cited in an appendix, making it accessible to general readers while remaining useful to researchers. A distinctive feature of Dixon's approach is his attempt to draw conclusions about the historical transmission and diffusion of myths across Oceania and into adjacent lands, not merely cataloguing stories but tracing patterns of contact and origin. He candidly acknowledges the work's limitations: missing sources due to wartime disruption, his own inadequate knowledge of Malay languages, and the speculative nature of his diffusionist conclusions. The preface conveys a preservationist urgency — Dixon explicitly hopes the work will spur collection of new material "while yet there is time" — reflecting the era's concern that indigenous oral traditions were disappearing.
