Many endangered, under-represented, minority and Indigenous language communities around the world need access to multilingual online resources to survive in the digital age. The Living Dictionaries platform provides a collaborative online space for professional linguists and citizen-linguists alike to produce their own grassroots digital dictionaries that include multimedia such as audio recordings and images. These online lexica can play an important role in assisting present and future generations in combatting language loss and creating visibility for their languages and cultures on the Internet.
