Four More Future Histories

Back To Methuselah by George Bernard Shaw.
The Galactic Center Saga by Gregory Benford.
A Short History of the Future by W. Warren Wagar.
The Third Millennium: A History Of The World: AD 2000-3000 by Brian Stableford and David Langford.

OK. I read Back To Methuselah once decades ago, have read perhaps two Galactic Center volumes and had not heard of the other two works until they appeared on recent Internet searches.

Blog readers will see that I have not kept up with contemporary sf and are invited to comment to that effect.
