This volume celebrates Robert B. Howell's wide-ranging contribution as a scholar, mentor, collaborator, and colleague in the field of Germanic linguistics. In addition to investigating present-day or past varieties of Afrikaans, Dutch, English, Flemish, German, and Pennsylvania Dutch, each of the thirteen contributions in this volume explores one or more of the topics found in Howell's work: (1) Linguistic structure and change (Page, Sundquist, Fagan, De Vaan); (2) Migration, contact, and change (Fertig, Louden, Roberge); (3) Vernacular sources and change (Auer & Gordon, Hendriks, Van der Wal); (4) Historical sociolinguistics: past, present, and future (Van Bree, Crombez, Vandenbussche & Vosters, Lauersdorf & Salmons).
