I just got my sis-in-law to give me her password for her library account so I borrow e-books from the library.  However, it says they need to be downloaded using ADE, and I've never used it.  I am relatively familiar with Calibre.  In anyone else's experience, do the books truly have to be downloaded w/ ADE, and can I still load them with Calibre?

I don't want to have to use 2 programs if I don't have to.  If I truly have to, then I will, but I won't like it.

Yes, they do. But, you can easily just use ADE for library books only and use Calibre for the rest.

I was using ADE long before Calibre.  You can run them both just fine.

ADE is pretty simple to use, not as many features as Calibre.

After much question asking on here, I ended up just downloading them both. ADE is easy to use. I haven't used Calibre yet since I don't download too many library books yet but I will use it as Emily does if I ever do get to that point. Once I got over the fear of doing all this, I've found it quite simple.

I don't do the unlocking yet to remove DRM -- I just download compatible books for right now, which is not big deal using Overdrive.

Exactly.

I started with ADE because I originally got my Nook a year and a half ago solely to read library books with and that's how you have to do it. BTW, you can use multiple libraries with no problem if you get to that point. I bought a few direct from B&N and was cool there too. Then when I started noticing that Amazon had some books available that I wanted to read that B&N didn't (or at a much cheaper price), that's when I explored the Calibre and the DRM stripping. That was only a couple of months ago. And, I wll say, B&N as an equal amount of unique books and authors under their independent published as AMazon does. BUt they have different authors signed up and I like being able to use and buy both.

I do have all my files stored on a flash drive rightnow and if they ever figure out a legal way for us to share, I'm ready. But so far, the only thing I've used Calibre for is converting a Kindle file to an epub to read on a Nook. I will tell you this though. If you borrow a book from a friend under the Kindle loan program and it downloads into you Kindle for PC (fully legal) just like any other book you buy from them downloads to your Kindle fr PC nd then you convert that book at Calibre, it disappears from your Kindle for PC folder in the 14 loan, but it doesn't remove from your Nook.

Sorry about the formatting. The box is doing that weird delete dela so I can't correct my typos.
