HELP! Bram Stokers Dracula-are versions different length because parts are cut out?

I wanted to find Dracula by Bram Stoker, so went on www.waterstones.com. I got on there, and several different copies of the book were listed, but all with different page numbers. Is it exactly the same story, or have bits been edited and cut out? I want one with the most of the origional story in it:/
