After a year’s silence, I write to memorialize the following:

• Every note that Rebecca Clarke wrote for performance and left in a performable state has now been published—admittedly, by six different publishers, but a Gesamtausgabe is a Gesamtausgabe, no matter how you slice it, and hello, Bach and Beethoven.
• Every note that Clarke wrote for voices and left in a performable state has now been published and recorded.
• Every note that Clarke wrote for instruments and left in a performable state has now been published, and virtually every bit of that has been recorded.
• The remainder, consisting of a single counterpoint exercise and two fragments, is in the works.

Details may be seen here, here, and here. I rest my case.
