RE: EPUB usage

Thanks, Rick. That is really interesting. Do you happen to have info on EPUB 2 vs 3? I seem to recall that VitalSource entered the game after EPUB 3, so I suspect you skew heavily toward EPUB 3.

This article [1] by Ben Dugas of Kobo is related and a little disheartening. (If any of you want to write for EPUBSecrets, contact Laura Brady.)

I’ve shared these numbers with you before (for 2016), but I just ran the 2017 ones, and I thought you would all appreciate them.
