This book is dedicated to Anna Siewierska, who died, far too young, in 2011. It gathers contributions by the foremost scholars in the field of linguistic typology. They discuss topics that are prominent in Anna's work, taking either a typological or a more language specific perspective. Mindful of Anna's last monograph, Person, the majority of the articles discuss person forms, reference tracking and related issues. Further topics are grammatical alignment, voice, ditransitives, and word order.
