A generation ago K.V. Sinclair published what is still the standard guide to medieval manuscripts held in Australia. The title defines the scope: Descriptive Catalogue of the Medieval Western Manuscripts in Australian Collections. The parameters are further delimited by date: included are MSS of the Xlth-XVIth centuries. Brim full with technical information, and perhaps as a result rather austere in presentation, this book is a testimony to Sinclair's perseverance: the completed manuscript was lost at the end of the 1950s, and he started again. One consequence of this setback is that the addenda to the main catalogue update a work that was largely finished over thirty years ago; yet even these additions were not able to take account of some items which came to Australia at the end of the 1950s.
