1008 :)
By my count.
Which means well over 1,000 ebooks on my Kindle Oasis that I got last year as a Christmas gift.
It has been a great journey (in acquiring).
There will be a great many more (in reading).
My Kindle Oasis still has 1.338 GB free.
They come with 4 GB.
I have more cookbooks than that, mostly Epubs though. I use Calibre on my PC and Moon Reader on my Android tablet. There are Kindle programs and apps. I’ve installed them but prefer Epubs to Azw3.
