This chapter explores the real-world applications of the Catalogue of Endangered Languages and the Endangered Languages Project. The project provides resources not only for academics but also for teachers, students, and endangered language communities. The chapter discusses the features of the website designed specifically with community needs in mind, including discussion forums for networking and a collection of approximately 6,500 audio-visual and text resources which complements the core content of the Catalogue. It outlines several cases where the Catalogue has aided in community projects, and discusses applications of the Catalogue for funding, awareness, and advocacy for endangered languages. Internal awareness and language management refers to how information about a language's vitality impacts the speaker community. A primary function of the Endangered Languages Project (ELP) site outside of the information associated with the Catalogue is to give community members and stakeholders a voice on the site.
