I once had a large library of books but my wife told me to downsize so I switched to electronic books.

I prefer the epub format and started with a Kobo reader but now I use a 7inch Lenovo tablet using Moon app.

I now have a huge electronic library that can be contained on a single USB drive.

I recommend to download as Bobbin does and use a Lenovo at about $90.
