As Pamela notes--if you owned them on Kindle or Audible pre-January, then they definitely count. Also--if you owned the book in hard copy pre-January, but want to use Kindle or Audible while you travel, then that is okay too. As long as you own any copy before January, it doesn't matter what version you actually read.
