We wish to acknowledge the vital work of these researchers. In addition to these written sources, we collected a large amount of information from various participants in the project. Most of the sources above also benefitted from local knowledge and each source provides a list of the informants who participated in their research.

Furthermore, we have sought to link the placename entries on the map to relevant information in the following external collections:

We welcome suggestions as to any further valuable links which may be created.
