In the letterpress edition of the Papers of James Madison, each volume is indexed separately. The indexes in this Rotunda edition follow this arragement; no attempt has been made to consolidate indexes that are separate in the letterpress volumes.
The entry/subentry structure for all index entries is derived from automatic processing. In the Madison Papers index entries, phrases identifying individuals are often provided as if they were subentry heads. For example, from the printed index:
Saurel (Sorrel), Joseph: Spanish commandant at Attakapas, 379 n. 3
In the digital index the page reference will appear under main entry Saurel (Sorrel), Joseph and subentry Spanish commandant at Attakapas.
