Field recordings are the data from which CA research proceeds. Keeping recordings well organized and accessible, securely backed up, and as reusable as possible is important for avoiding data loss, enabling collaboration, and ensuring future uses of the data. In this chapter, we outline some essential data management practices for backing up, encrypting, and sharing data. We explain how conversation analysts organize audiovisual files, transcripts, and metadata. We also help the reader to navigate the complexities of dealing with multiple recording sources, and for choosing digital file formats and codecs. This chapter aims to support CA researchers from the first moment of having recorded some interactional field data to the point of being ready to start doing detailed forms of analysis.
