This is a higher level grouping of all series whose content includes specific linguistic materials relating to languages from Melanesia and Oceania. The areas covered include (more generally) Papua New Guniea, West Irian, the Solomon Islands, (and more specifically) Baik, Numfor, parts of Waigeo, the Yapen Islands, Taqula Island, and Rossel Island. The series include material on Proto-Oceanic linguistic studies, field note books, printed publications on grammar, comparative vocabulary lists (often in Capell’s own notebooks), and texts in local languages.
Oceania is a geographical (often geopolitical) region consisting of numerous countries and territories – mostly islands – in the Pacific Ocean. The exact scope of Oceania is controversial, with varying interpretations including East Timor, Australia, New Zealand, or none of these.

Melanesia is a region extending from the western side of East Pacific to the Arafura Sea, north and north-east of Australia. The term was first used by Jules Dumont d'Urville in 1832 to denote an ethnic and geographical grouping of islands distinct from Polynesia and Micronesia. Today d'Urville's racial classification is known to be inaccurate because it obscures Melanesia's cultural, linguistic, and genetic diversity. Most importantly, this term combines two quite distinct groups, the Austronesians and the Papuans (who themselves can be considered as comprising a number of distinct groups).
