There are currently 15 languages from this region in the project.
The relevant Holle lists can be found in volume 8 of Stokhof & Saleh-Bronkhorst.

To add a missing language,
or correct a misplaced one, please use the Contribute page.

This list will eventually be incorporated into the map, but for now I'll stick it here:
