Preface
This catalogue has evolved gradually over the years in response to the need I have increasingly felt as a reader and teacher of Chaucer to examine the primary evidence behind some major textual problems where the editions and the dependent critical mass have glossed over or failed altogether to report the difficulties.

Introduction
The eighty-eight manuscripts and fragments which are catalogued in this volume include all known copies of Chaucer's work except the Canterbury Tales (to appear in Volume II) and a few stray copies of lyrics and other small poems which occur elsewhere without other Chaucerian association.
