The Resource Network for Linguistic Diversity (RNLD) links language maintenance practitioners to share methods, resources, practical advice and weblinks to relevant sites for working with endangered languages. People involved in language work may be speakers of indigenous languages and their descendents, linguists, staff of language centres, educators (in many different educational settings), archivists, specialists in the development of appropriate technology, and key regional institutions (community, government, nongovernment).

The Network focuses on language maintenance activities in the region broadly bounded by Australia, Indonesia, East Timor, Malaysia, Brunei and Melanesia - a region marked by high levels of both linguistic diversity and language endangerment.

RNLD provides a means of linking newcomers to the field with experienced practitioners, as well as providing advice on issues that are commonly encountered, for example:
* methods in language documentation
* training programs which can provide language activists with necessary skills
* appropriate technological approaches to language data
* techniques for producing archival recordings
* research methods for locating and interpreting archival material for linguistic and cultural revival
* dictionary production
* links to expertise in associated fields
