The same numbering scheme is used in the 1985 Éditions de l'Oiseau-Lyre edition, as well as in the first complete harpsichord works recording, by Davitt Moroney.
The vast majority of Couperin's organ pieces—the contents of the so-called Oldham manuscript—were unknown until 1957, and remained unpublished until 2003.
The numbering in the following list is derived from the Éditions de l'Oiseau-Lyre (OL) edition (Monaco, 2003, 135 p.), the only available as of 2016 (but indefinitely out of print).
Many of the pieces in the Oldham manuscript (still unavailable) are inscribed with the date of composition and/or the composer's name; these notices are reproduced here (with respect to the original spelling and punctuation) to facilitate navigation.
