As I write the introduction to my penultimate volume of the Annual Review of Applied Linguistics, I find myself grateful for three aspects of the job. First, I have learned so much about research that I did not know existed, in the case of this issue, linguistic landscape research. Second, I am grateful for colleagues who, while experts in their specific areas, have an amazing breadth of knowledge of the field of applied linguistics. Such individuals are rare finds, and I am lucky to have several such people on my editorial board. Finally, I would not be able to put together issues on certain topics without the help of colleagues whom I have called upon for brainstorming sessions. I am thankful for colleagues who are so willing to help. For this issue, I thank, in particular, Jasone Cenoz.
This volume focuses on research in multilingualism from a wide variety of areas. Some of the articles focus on cognitive factors related to an individual's multilingualism, and others focus on multilingualism in various social contexts. In addition to helping the editorial directors and me determine topics and authors, Jasone Cenoz agreed to write the introduction to this volume, in which she discusses the rise in the focus on multilingualism in a variety areas as well ways that multilingualism has been defined. I will let her article speak for itself, but for the purposes of this volume, I simply told the authors that they needed to include research that addressed more than two languages.
As in the past, review articles in the Annual Review of Applied Linguistics are expected to focus on recent research. Of course, sometimes the authors need to refer to older research to define terms or set the context for more current research. I have tried to make the articles accessible to readers who are not experts in the individual areas.
As always, I thank the editorial directors for their review work and for their input on the contents of the journal. In addition, I am grateful to the reviewers who gave their time and expertise. These reviewers include Jeff Bale, Debra Friedman, Aline Godfroid, Jan Hulstijn, Ajit Mohanty, Jonathan Newton, Aneta Pavlenko, Vai Ramanathan, Virginia Yip, and seven anonymous reviewers. Sally Behrenwald, again, has contributed her editing skills and APA expertise. Finally, from Cambridge University Press, I think Morrell Gillette for his patience; Laura Etheredge, our former editor, for her hard work and enthusiasm in promoting the journal; and Melissa Good, our current editor, who after only a short time has already shown great interest in the journal.
