Good Books?

Looking on Amazon for a good book or two on Norton Commando's. Below are a few that I found. Since none of the books had reader reviews, I'd be interested to know if any can be recommended by the forum. Any others out there I should be looking for?

Thanks

Norton Commando (Haynes Great Bikes) by Mick Duckworth

Norton Commando: Ultimate Portfolio (Paperback) by R.M. Clarke

Norton Commando Owners Workshop Manual: Chilton

NORTON MOTORCYCLES FACTORY WORKSHOP MANUAL 1957-1970 (Paperback) by Norton Manufacturing Co. Ltd.

Norton Motorcycles: From 1950 to 1986 (British Motor cycles since 1950) (Hardcover) by Steve Wilson

I bought this one: Norton Commando (Haynes Great Bikes) by Mick Duckworth before I bought my MKIII Commando. All I needed was something to familiarize myself with them.

I tell you though, this forum is better than any book I read.

Great references. Thanks.
