This page used to host a tool called ConvertLit. Technically it still does; you can download open_c-lit-1.8.tar.gz if you wish. However, you no longer need to. We won! Microsoft completely retired their Reader and the .LIT file format is dead.
If have any .LIT files still trapped in their DRM, you can rescue them with Calibre and DeDRM tools, which supports freeing your eBooks from most other DRM schemes.
If you're looking for more details of the original ConvertLit software, visit convertlit.com.
I still recommend: do not buy DRM-encumbered eBooks. Buy open eBooks. Places you can get open eBooks.
The Right To Read is a parable set in a dystopian future where every book read must be strictly accounted and paid for. Don't let it come to fruition. Demand to have ridiculous laws like the DMCA repealed. Join the EFF. Don't just sit there and take it.
