Are there any scientifically based books on memorization techniques

[Diamond]

Many moons ago I bought the "Mega Memory" book by Kevin Trudeau. Then I found out who Kevin Trudeau was, and I sold the book to some other gullible idiot.

As I get older, remembering important facts is getting harder. Are there any good books on memorization, exam techniques etc that skeptics here would recommend?

Harry Lorayne has several good books on this.
