"Triple Your Reading Speed" by Wade E. Cutler is the best I've seen. He discourages using your hand but the Mega Speedreading drills are easy to do too and do work if you keep it up. A 5 minute warm up drill in the morning lasts all day. All the speedreading books all say the same thing, more or less. If you just practice reading faster you'll get faster and invent your own way.
