OLAC

OLAC, the Open Language Archives Community, is an initiative to create a unified means of searching online databases of language resources for linguistic research and other purposes. The information about resources is stored in XML format for easy searching. OLAC was founded in 2000. It was hosted at the Linguistic Data Consortium webserver at the University of Pennsylvania until 2026, when the hosting was moved to the University of Cologne.

OLAC advises on best practices in language archiving, and works to promote interoperation between language archives.
