Baseball Cards Price

in the beckett price guides is mass market paperback different-10 points?

I am thinking about buying a 2010 beckett baseball card price guide off amazon for 8.99 (Mass Market Version) the regular sized paperback is more expensive (about 29.99) but it has more pages (Mass Market has 672 and regular has 800) can anyone tell me the difference between the two.
