The early chapters discuss libraries in antiquity, notably at Alexandria and republican and imperial Rome, and also the Christian libraries of late antiquity which supplied books to Anglo-Saxon England. Because Anglo-Saxon libraries themselves have almost completely vanished, three classes of evidence need to be combined in order to form a detailed impression of their holdings: surviving inventories, surviving manuscripts, and citations of classical and patristic works by Anglo-Saxon authors themselves.
After setting out the problems entailed in using such evidence, the book is provided with appendices containing editions of all surviving Anglo-Saxon inventories, lists of all Anglo-Saxon manuscripts exported to continental libraries during the eighth century and then all manuscripts re-imported into England in the tenth, as well as a catalogue of all citations of classical and patristic literature by Anglo-Saxon authors.
