Documentary linguistics is a major subfield of linguistics interested in the creation of lasting, multi-purpose records of languages. This talk provides an in-depth look at one such documentary linguistic project – a project documenting the Hadza language, funded by the Endangered Languages Documentation Programme (ELDP), which took place from 2019 to 2021. Following some brief context, both on the Hadza language and on the researchers, the talk 1) presents the documentary project in a stepwise fashion from preparation to project setup to daily activities to archiving; 2) reviews some outputs of the project, and 3) reflects on feedback from the Hadza people themselves who were involved in the documentary project. Note: This talk has not gone through a process of peer review, and findings should therefore be treated as preliminary and subject to change. Acknowledgement and citation: Harvey, Andrew. 2022.
