Good Sicilian Book

Right now I usually use the Sicilian vs e4, but there are a ton of variations apparently.  Any suggestions on which variations are "better" and if there are any good books on the Sicilian.  Thanks.

I use the najdorf, but that's just me personally. I've heard that "starting out the sicilain defense" is a good book. In addition, you may be interested in http://www.chess.com/groups/view/the-sicilian-superstars. Happy sicilaining to you

I haven't studied enough or otherwise learned enough about chess and openings, etc. to know very many of the names.  While I may use what is called one type of opening or another, I really don't know enough about the game to identify which openings I'm using most of the time.  There seems to be a name for practically everything, but I haven't learned the language yet.
