Notes:

1. The table aboves shows the selections included on the recording. Thanks to Chris Webster for providing the details where there are multiple items on a side. (Francis shows just the first item on each side.)
2. The selections are numbered consecutively from 1 to 19, as shown above. Three of the Columbia sets are similarly numbered, but for The Mikado they used "a" and "b" to distinguish multiple selections on the same side.
3. The matrix numbers for the Columbia Iolanthe, Mikado and Yeomen were pre-assigned in the issue sequence of the selections; hence, unlike many of the HMV 78rpm sets, one cannot determine the recording order by sorting the matrix numbers. From the Recording Date column, however, one can see that the company recorded three sides per day on each of two days (8 and 10 June), and the other six sides on 9 June. This observation certainly puts the "take numbers" (a "-1" or "-2" after the base matrix number) in question. If, as these numbers suggest, the first take was published for eight of the sides, and the second take for the remaining four, it should have been possible to record more than 3 sides on 8 and 10 June.
4. Webster reports that all of the Columbia sets were published in two versions: "laminated records which have a solid gold ring around the label; and shellac records which have the outer gold ring broken at the top by the words 'Made in England', and broken at the bottom by the record company's details." Laminated pressings never included the take number after the base matrix number. Shellac pressings often gave the take number, but not always.
5. As published in England, the Columbia sets (except for The Mikado) did not include side numbers. They are supplied above for ease of reference. James Tappin reports that an American Columbia Iolanthe set that he owns does have side numbers.
6. Francis says that no conductor was indicated in Columbia's daybook for sides 2, 10, and 11. It may, or may not, have been Batten.
