Memory workout

Does anybody know book titles or authors on the subject of memory training (extreme !!)
Thank you

 

Yeah, I know a few... I forgot the names of them though. Sorry.

 

Hard to go wrong with anything by Harry Lorayne, e.g., "The Memory Book."

 

The Memory Optimizer by paul scheele.. I have it saved on my hard drive, I believe it is a 7 disc series.. PM me.

 

Glad it made such a memorable impact...lol.

 

Wasnt there some guy, who, i think had an infomercial thing, yeah, he was amazing.
