Language as it appears in the public space, often referred to as “linguistic landscape,” has been the object of serious academic study for over a decade, resulting in several singled-authored and edited volumes, numerous articles in international journals, theses, dissertations, eight international workshops on four continents and at least one dedicated web site. In Asia, studies have been conducted in Japan, China, Hong Kong, Cambodia, Malaysia, among other countries. A 515 item bibliography compiled by Chula alum Robert Troyer can be found at www.zotero.org > groups > linguistic landscape bibliography.
