Like its two predecessors, Aspects of Old Frisian Philology (1990) and Approaches to Old Frisian Philology (1998), Advances in Old Frisian Philology combines contributions by specialists of medieval Frisian studies with papers by international specialists from adjacent fields who have been invited for the occasion to bring their expertise to the discipline of Old Frisian. Together, the diverse approaches considerably advance our knowledge of and insight into various aspects of Old Frisian philology.

This is the first text book to offer a comprehensive approach to Old Frisian and includes a history of the Frisians during the Middle Ages, their society and literary culture. Covered are the phonology, morphology, word formation and syntax of Old Frisian, with a chapter on Old Frisian dialects and one on problems regarding the periodization of Frisian and the close relationship between (Old) Frisian and (Old) English. Included is a reader with a representative selection of twenty-one texts with explanatory notes and a full glossary. A bibliography and a select index complete the book.

This bibliography aims serve the demands and wishes of students of Old Frisian for its own sake as well as for those who want to use Old Frisian for comparative purposes. Although it concentrates on language and literature, titles have also been included which deal with more or less peripheral matters such as Ingvaeonic, history, legal history and daily life in Medieval Frisia. The bibliography is divided into three parts. Part I lists in alphabetical order all the books and articles. Part II alphabetically indexes the reviewers occurring in Part I. Part III contains an analytical index to Part I, enabling scholars to survey what work has been done on a particular subject.

The language of the First Riustring Manuscript, dating from ca. 1300 AD, represents the most archaic stage of Old Frisian. The mainly legal texts are famous for their historical value. However, a grammatical treatise of this important codex is still lacking. This book is meant to meet this need. It contains an inventory of the linguistic evidence as well as a synchronic study of the grammar. Moreover, historical linguistic problems are discussed wherever relevant. The book is intended for all students of Old Frisian, not just linguists but also legal historians, philologists, historians, and others.
