This series chiefly working materials of David Hyndman (plus a few holiday photos). This include a large body of slides and photographs generated largely during field work in Papua New Guinea among Wopkaimin speakers in the mid 1970s and again in the early 1980s while studying the environmental impact of the Ok Tedi mine. There is also photographic material from the Philippines, focused on the southern Cotabato region. Hyndman also recorded some twenty-nine audio cassettes during his early field work in Papua New Guinea - these include songs, storytelling, and zoological samples. e.g. frog calls. His recordings are cross referenced and sometimes transcribed in his field notebooks, of which over forty are included in this series. In addition the series contains preparatory material for publications and botanical information.

The series also contains material generated by others, notably ethnologist Wilson Wheatcroft, who provided Hyndman with translations of traditional stories and legends of the Tifalmin people of Papua New Guinea.
