In my previous post I had linked to the Internet Archive.
I recommend one book that you’ll find there, The French Revolution by the historian and satirical writer Thomas Carlyle. Besides the HTML version the IA also offers the book in a number of other formats.
Carlyle’s prose is very much a matter of taste. If you are interested in the subject matter and enjoy his eccentric and heavily metaphorical style of writing you are in for a real treat.
