It is a sign of overweening ambition if not hubris to think that all of applied linguistics can fit between two covers. Dynamic even when the Annual Review of Applied Linguistics (ARAL) began publication in 1981, applied linguistics has continued to change, grow, and redefine its areas of coverage, even as many other journals have emerged in the intervening 25 years. Writing in the 20th anniversary issue of ARAL, my editorial predecessors, Robert Kaplan and William Grabe, provide the historical context for the establishment of ARAL and show how it came to fit into the context of applied linguistics as the field evolved from the mid-20th century to the beginning of the 21st. They summarize the key notions that characterize applied linguistics and remark that it “commonly includes a core set of issues and practices that are readily identified as work done by many applied linguists (language teaching, language teacher preparation, and language curriculum development)” along with “several further identifiable subfields of study: bilingual studies, corpus linguistics, forensic linguistics, language contact studies, language testing, language translation and interpretation, language use in professional contexts, lexicography and dictionary making, literacy, second language acquisition, and second language writing research” (Kaplan & Grabe, 2000, p. 5). The variety and diversity of these subfields defy attempts to gather them into a single volume (although some useful recent handbooks have done so; see, for example, Davies & Elder, 2004; Kaplan, 2002); furthermore, at present, topics in applied linguistics are commonly addressed through entire handbooks for particular subfields (Bhatia & Ritchie, 2004; Doughty & Long, 2003; Spolsky, 1999) or even in multivolume sets such as the Encyclopedia of Language and Education (Corson, 1997). Hence, this year's volume should perhaps be labeled a ‘selective’ survey, or even a sampling of the field, rather than an exhaustive inventory of all possible endeavors that warrant inclusion within applied linguistics. The present volume features research on some of the perennial concerns of applied linguistics, akin to Kaplan and Grabe's ‘core issues.’
