Re: EPUB usage

A bit of a follow-up on this.  Looking at our sister company CoreSource, we have received:

EPUB 2 from 9430 publishers for a total of 1,004,545 titles
EPUB 2.0.1 from 2133 publishers for a total of 39,779 titles
EPUB 3 from 2117 publishers for a total of 85,480 titles
EUB 3.0.1 from 1013 publishers for a total of 25,272 titles

That’s a Grand Total of 14,693 publishers delivering 1,155,076 EPUB titles.

HOWEVER….

If you just look at deliveries in 2017, there were 2,148 publishers who delivered 40,130 new EPUB 2 files, and 1,018 publishers who delivered 25,737 EPUB 3 files.

And…

If you look at deliveries over the past 12 months, there were 4,403 publishers who delivered 844,270 new EPUB 2 files, and 1,895 publishers who delivered 106,428 EPUB 3 files.

Those EPUB2 publishers need to be a target of our marketing!

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.
