A stated goal of language documentation is to make language resources available for use in language revitalization. This chapter identifies some limitations and challenges of working with language documentation materials, particularly legacy (historical) documents and resources in digital language archives. It then suggests ways that language documenters can make their work more useful for revitalization purposes. It identifies often-ignored areas that documentation should target, such as family language, everyday usage and young people’s speech, and suggests further contextual information and metadata that should be included. Language revitalizers can also adopt the methods, practices and tools of language documenters and should be encouraged to document the processes, decision-making, events, successes and failures of their work so that they and others can learn from them. The capsules present technical advice on making audio and video language documentation recordings; a community-based research model for field methods courses on revitalization; and outcomes of a pilot study on Alznerish conducted during a field school in Poland, with methodological proposals for short-term studies.
