Standard Ebooks is an awesome long overdue idea:
Standard Ebooks is a volunteer driven, not-for-profit project that produces lovingly formatted, open source, and free public domain ebooks.
Ebook projects like Project Gutenberg transcribe ebooks and make them available for the widest number of reading devices. Standard Ebooks takes ebooks from sources like Project Gutenberg, formats and typesets them using a carefully designed and professional-grade style guide, lightly modernizes them, fully proofreads and corrects them, and then builds them to take advantage of state-of-the-art ereader and browser technology.
What a great project.
