[MARGINAL NOTES]
Headnotes have been moved to the beginning of the appropriate paragraph. Headnotes were omitted from the two Appendixes, as sidenotes give the same information.
Line Numbers are cited in the Index and Glossary. They have been omitted from the e-text except in the one verse selection (App. II, Carmen de Algorismo). Instead, the Index and Glossary are linked directly to each word.
Numbered Notes:
Numbered sidenotes show page or leaf numbers from the original MSS. In the e-text, sidenote numbers have been replaced with simple asterisks.
Footnotes give textual information such as variant readings. They have been numbered sequentially within each title.
Sidenotes giving a running synopsis of the text have been kept as close as possible to their original format and location.
