From their website:
Standard Ebooks is a volunteer driven, not-for-profit project that produces new editions of public domain ebooks that are lovingly formatted, open source, and free.
I wanted to share this, because I think this is an awesome education resource for comrades, ebook enthusiasts, and just everyone!
And yes, they do have "The Communist Manifesto," but not any other Marxist literature that I know of. Feel free to contribute.
This is awesome, thanks for putting it out there. Looks like they don't have any Proust, so might start contributing!
