Stephens (1982:7-8) "I am a native speaker of the dialect of Bro-Dreger, having learned French only when I went to school. Most of my study will be based on my experience with and knowledge of that dialect. I should remark, however, that I have examined sources from all the other dalects including Bro-Wened. These are available in a number of publications in Breton, such as Al Liamm, Hor Yezh, Pobl Vreizh, Barr-Heol, Brud Nevez, Skrid, Al Lanv, Evit ar Brezhoneg. An important other source is the collection of the spoken Breton of Bro-Dreger by Jules Gros (1970, a, b, 1974). Gros, himself a native speaker of the dialect of Bro-Dreger, carefully compiled a collection of Breton as it was spoken, in the first part of this century [XX°]. [...] There exist also monthly magazines on audio tape cassettes: Kazetenn ar Vro Plinn, Kazetenn Bro-Dreger, Kazetenn ar Menez, for example, which proved to be valuable sources of material. The speakers on Kazetenn Bro-Dreger speak in the dialect of Bro-Dreger, but Bro-Plin being close to the South, includes speakers from different dialects. Finally, during regular visits to Brittany, I have been able to consult neighbours and members of my family, all native speakers of Breton, and for whom Breton is still the everyday language."
