This book is a rigorous and broad update of the state of the art in the investigation of Old and Middle English. The volume, written by some of the best known experts in this field, addresses different issues, such as etymology, manuscript sources, and medieval literary traditions, among others. Its contents will be particularly useful for those interested in the different perspectives of current research in the field, exhorting the reader to consider the relationship of the medieval textual heritage and language with both its contemporary medieval audience and the readers of the 21st century. This book will appeal to specialists in Old and Middle English language and literature and also to university students. In contrast with monographs, which focus on a specific aspect, these essays allow a broader panorama of what is being done and the approaches currently being used.
