A:AnswerIts a model year 2019, so probably late 2018 through 2019 is my best guess on manufactured date. I'm not positive, but I would imagine they would quit manufacturing them in 2020 to make room for a new model, but I could be wrong.
A:AnswerGoogle play books has a library button on the bottom center of the screen using Google Play books app.
There's home/library/shop all at the bottom of the screen.
Nook is different. I usually press a button or click on the library option also at the bottom of the screen. after pressing the n button.
nook is sometimes tricky with thier options.
Amazon kindle has the options on the bottom of the screen too...in teeny tiney letters. Library is second from the left.
Hope this helps
