Ok, I made it! It's more difficult without Overdrive App, but it will just take me getting used to searching on my laptop, "borrowing" the book I want from my library, then transferring it via my USB cord.
Then I had to go into "My Stuff" to find "files", "digital editions" and finally, there was my book I had 12 days left on. Hope this all makes sense. I was nearly ready to just go out and buy a newer Nook, or something else, that the Overdrive still works on.
Thanks to you all, I can keep on using this Nook though, until it becomes totally worn out, LOL!! Thanks again everyone
