Punctuation and capitalization are kept to a minimum; ‘i’ is preferred to ‘j’, and ‘v’ to ‘u’ in, for example, vendere. In the texts supplied material is placed in square brackets, doubtful material in round brackets. In general only significant textual variations or difficulties, such as some incorrect grammar, are noted. In the summaries supplied or doubtful materials are placed in square brackets, and where possible proper names are identified and modernized; italics are employed for technical terms and for unidentified places and persons. Most of the texts are contemporary registered copies rather than originals. In some cases they are almost or partly illegible. Their abbreviations are often heavy with frequent use of etc. Contracted forms often make it difficult to distinguish a Magistral from a Conventual bull. Modern pencil foliations in the registers are added in round brackets where they exist.
