This volume will be of particular interest to readers interested in expanding the applications of corpuslinguistics techniques through new tools and approaches. The text includes selected papers from the Fifth North American Symposium, hosted by theLinguistics Department at Montclair State University in Montclair New Jersey in May 2004. The symposium papers represented several areas of corpus studies including language development, syntactic analysis, pragmatics and discourse, language change, register variation, corpus creation and annotation, and practical applications of corpus work, primarily in language teaching, but also in medical training and machine translation.
