I have two endgame books right now, 100 endgames you must know by gm jesus de la villa and Dvoretskys endgame manual, which one should i go through first. 

Mark Dvororetskys endgame manual is on a really high level, and besides from the first few pages, there is very little in there aimed at a beginner or intermediate player.

If your a beginner pandolfini is always good.

First one to read: Pandolfini's Endgame book

First one to buy: More great options. Silman's

http://www.amazon.com/Silmans-Complete-Endgame-Course-Beginner/dp/1890085103

is liked by many here, and I know of a 1900 USCF who loves it, so let's call that one a reasonable option.

So borrow the Pandolfini from someone or the library and if you feel like more after this simple book, then you can buy a good one of your choice--and there are a few to pick from.

Here's a recent thread with info on endgame books

Definately the 100 must know endgames.  I got Dvoretskys endgame manual but before going through it skimmed/re-read seriwans winning chess endgame book and went though all the puzzles in "practical chess endings."

Dvoretsky's book is fantastic, but almost so much as to be a reference book -- even so, I definitely recommend going through the whole thing -- there's no way I absorbed all of it the first time, but my play noticably improved.  (Which is the great thing about studying endgames is it improves your entire play, not just in endgames).

When you do get into Dvoretsky's book, don't get discouraged :) the first chapter is probably the hardest (or it was for me).  I still have trouble finding corresponding squares and all that.  Also the rook chapter seemed to last forever.  In the end it was worth it though.

thanks guys i appreciate the help

Silmans for sure. it goes by level so you can always build up

Pandolfini has written more than a few books that rightly get panned, but I found his endgame book worth the purchase and read. There are however many errors that need correction (I pencilled mine in).

See http://glennwilson.com/chess/books/pec_errata.html

I agree the Silman book (weighing in at 2.5 pounds!) is the next step if not the first one.

As much as I like endings and Dvoretsky, I caution on this path until the basics are thoroughly understood. (I have & love this book, but then again, I like reading encyclopedias.)

 I too struggled with Fine's BCE, and given the volume of errata published over the years no one should rely upon the analysis too closely.

Averbakh's Chess Endings:  Essential Knowledge was just that, an ideal basic text on the ending. 

I have the updated and corrected BCE but still not for beginners.  It is fun however.  I always liked Keres' book.  "Purdy on the Endgame" by CJS Purdy is good as well.  The sections Lasker and Capablanca put in their primers is also valuable or Howowitz How to win the in the chess ending.  As endgames don't change much old endgame books retain their value.  You should be able to find a good variety at a good price through used book stores and sites.  Just going through a endgame column on a regular basis can make a world of difference.
