This 500-page bibliographical supplement has been revised and expanded for the completion of the DI's first four volumes, devoted to geographical names. It records the broad spectrum of materials that inform the DI - Italian dictionaries, literary and historiographical sources, electronic corpora - and updates the original 100-page Supplemento bibliografico published in 1997.
