This volume will be of particular interest to readers interested in expanding the applications of corpus linguistics techniques through new tools and approaches. The text includes selected papers from the Fifth North American Symposium, hosted by the Linguistics 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. A common thread through most of the papers was the use of corpora to study domains longer than the word. Not surprisingly, fully half of the papers deal with the computational tools and linguistic strategies needed to search for and analyze these longer spans of language while most of the remaining papers examine particular syntactic and rhetorical properties of one or more corpora.
