How Do I Read Library Books on My Kindle? Part 2: ePub
Last month I figured out how to put Mobipocket format books on the Kindle. Unfortunately, that leaves out the vast majority of library books out there, which are in ePub format. I put off figuring out ePub this long because I thought it was going to be much more complicated, but it’s actually not. However, most ePub books are Adobe ePub, and therefore DRM-protected, so we’re wading into an ethical gray area. But let’s deal with the unprotected kind first.
Unprotected ePubs
These are available, for example, at Google Books and Project Gutenberg. All you have to do is change the format to one that can be read on the Kindle: specifically, Mobipocket.
The first time:
- Download the Calibre program. Move it to Applications.
- Open it and run the welcome wizard (under the Tools icon in the top right corner, if it doesn’t start automatically).
Each time you download a book:
- Click the Add Book icon in the upper left corner and choose the book you downloaded.
- Highlight the new book and click the Convert Book icon at the top.
- Once it’s done converting, and your Kindle is plugged in to the computer, click the Send to Device icon at the top. I said it was easy, didn’t I?
DRM-Protected ePubs
In order to convert an Adobe ePub book with DRM to a format readable by the Kindle, the DRM has to be completely stripped. This removes the software that makes a library book expire after its due date, so it’s technically illegal. Personally, I would feel comfortable doing this because it’s a library book, not something stolen, and I’d be reading it once, not putting it online or trying to sell it. But you make your own call.
The first time:
- Install Digital Editions.
- Go to this blog and download both the key-retrieval script and the decryption script.
- Double click “ineptkey.py”
- This will bring up an IDLE window. In the menu, click Run, then Run Module.
- You should get a pop-up window that says “Key successfully retrieved to adeptkey.der.” Keep this file. You’ll need that key to convert each book.
Each time you download a book:
- Double click the book file. This opens it in Digital Editions and converts it from .acsm to .epub.
- Double click “ineptepub.py”
- This will bring up an IDLE window. In the menu, click Run, then Run Module.
- You should get a pop-up window that says “Select files for decryption”. Choose the file you want to decrypt. It’s usually in Documents, Digital Editions.
- This should output an unprotected .epub file. Follow the steps above to convert it.
I think this may be even easier than making Mobipocket books readable on the Kindle, mostly because the Calibre program is awesome. But even after doing all this research, I don’t think I’m going to be using this information very often—it’s just so much easier finding books on Amazon than trolling through library sites.
