B&N calls it "sideloading."
If you casn download an eBook to your computer,
and if it is in a format that the Nook can understand
(which is most of them) then you can transfer it to your Nook.
As for your local library, it depends on whether you can
access them online, or if you can do it locally.
There are, literally, tens of thousands of free eBooks available.
In the past month, I have siodeloaded close to 50 eBooks, all for
free. My big problem is finding the time to read them (or listen
to them in the case of the free audio books) before I download more!
I've also added several images to my Nook for wallpaper and/or
screensavers. Although they are B&W, the resolution is pretty good!
I think I have made the right investment. My question is, how can I download and install on my Nook? I'd like to borrow books from the library mostly or any source the I can put on my nook. I am not interested in reading a book from my PC which is a MAC by the way.
Hope you can help me. I've exhausted every avenue I can think of.
