Can anybody recommend some science fiction written long ago with links to where the stories can be downloaded for free? The older the stories the better. The first thing that comes to mind is obviously the works of Jules Verne. It is interesting to see how people of the past thought what the future might look like and how those visions compares with how we live today.
"We" by Yevgeny Zamatin is pretty good, and is public domain so it should be pretty easy to find.
I have not read it all, but it is listed as one of the oldest SF stories ever.
