Digital language data provide accessible and enduring records for world languages. While legacy data collections may offer new insights into small or endangered languages, their digitization can raise practical challenges in terms of navigating vast databases of files with limited metadata. This paper demonstrates the practical benefits of creating a finding aid and inventory for a large collection of legacy data which has been converted to digital format. In so doing, it also provides a guide to the Alan T. Walker Collection for Lii Hawu, "the Hawu language" of Eastern Indonesian (also known variously as Havu, Sawu, Savu, and Sabu language). A guide to the Walker Collection was needed in order to more easily navigate its digital contents in PARADISEC (Pacific and Regional Archive for Digital Sources in Endangered Cultures). The Collection includes approximately 13 hours of digitized audio-cassette recordings and 7,425 digitized images from 43 scanned handwritten notebooks. The paper concludes with a brief consideration of the process of working with digitized legacy data and the benefits derived from creating a finding aid and inventory for such data.
