Lightbulb Converting old DRM'd books for use on a Sony Reader

Hi there,

There are a couple of options:

For LIT -
1. You're in luck here! Just download a program called ConvertLIT, which has a GUI called ConvertLIT GUI. As long as you have your MS REader on your computer activated to your MS Live Passport ID (you know this if you can read your ebooks in reader on your PC), you can then use ConvertLIT to strip out the DRM. Once the DRM is stripped, you can use another program, like libprs500 to convert it to LRF (Sony eReader) format.

For PDF -
The options here are harder, since the only PDF program that could remove DRM without a work around was made by a Russian programmer who got into very hot water for releasing it. It's impossible to find.

Your first question should be "Do your PDF files allow you to print them"?

If you can print, then here are your steps:
1. Either print it to a paper printer and thus kill a tree. Then use a scanner with an automatic document feeder to scan in the paper pages, while running it through an OCR program to save as RTF. Then use libprs500 to convert the file to LRF.
2. OR you can install a PDF converter program that can install a PDF file "printer" into your system. When you do that you'll be able to print your protected DRM'd PDF into an unprotected non-DRM'd PDF. Then you can use a PDF to RTF converter to convert the file to RTF and from there to LRF using libprs500. I would recommend trying PDF Converter 4 from Nuance - Scansoft. If someone knows of a freeware PDF to RTF converter, that would rock as well.

If you CANNOT print your PDFs:
1. Use a screen capture program to capture each page of the file to images, which can be run through an OCR program to switch them into RTF, and thence to LRF. SnagIT from TechSmith is a great choice, with a 30 day trial. I think that it also has an API so that you can write a script that would capture the screen every time it changes, so all you have to do is "page down" through the text and Snagit will capture the 100's of image files.

As you can see, it's possible. Much easier and automated in .LIT format than in PDF, and much easier in PDF if you can print. But as long as you can see the text on the computer screen, you can eventually convert it.

Good luck! and Best Wishes,
Eric
