Together with Robert A. Troyer we have just published a methodology-focused paper "Representation and videography in linguistic landscape studies" in the John Benjamins journal Linguistic Landscape which is the definitive journal of the field.
Our cooperation with Robert has been very stimulating and productive, and I hope that our further joint papers will also reach their readers soon.
