 The two abbreviations used in this entry, BOL and BOI, are defined below. The page numbers in BOL are indicated in the margins of many later editions and translations. Roman numbers following the abbreviations indicate volume numbers; an Arabic numeral immediately after a Roman numeral and full stop indicates a separately paginated part of a volume. Hence “BOL II.3, 213” designates Bruno, Opera latine scripta, volume II, part 3, page 213.
