Marx Reference Books/Sources?

I’m looking for good reference info on Marx trains such as model #s, years offered, maybe variations, etc…

What is the difference between Greenberg’s Marx books Volumes I, II etc?

Any other books anyone suggests?

Or good reference websites?

Thanks

Volume 1 covers steam and 6 inch cars. Volume 2 covers diesels sets, scale cars, and plastic (I think). Different editions may vary.

Thanks!
