A large number of language resources are available at the Endangered Languages Archive (ELAR)
The Endangered Language ARchive (ELAR) is a digital repository specialising in preserving and publishing endangered language documentation materials from around the world.
The ELAR Catalogue contains about 140 collections from around the world. Accessing information about the collections and metadata associated with the resources on the ELAR catalogue is available to all users. However, to view or download the materials, you will need to register for an ELAR user account. Since endangered languages materials can be associated with sensitivities, you will need to have the right level of access for the particular resource you would like to access.
