The highly regarded Children's Language series continues in 2001 with two new volumes, 10 and 11 (Nelson, Aksu-Koc, & Johnson, 2001, Vol. 11). Under the able leadership of Keith Nelson (who has edited all but two volumes), each volume since 1978 has represented current topics in research on child language; and the series provides a comprehensive overview of the history and progression of the study of language development over the past two and a half decades. Since Volume 7, the papers included in the series were chosen from the range of presentations at the meetings of the International Association of the Study of Child Language, which bring together researchers from Asia, Europe, the Middle East, Australia, North and South America, and Africa. Prior to Volume 7, articles in each volume also represented an international scope.
