Endgames chess book

Which book is best with getting pgn resources...?

Ahhh!!! Dvoretsky's endgame manual is available on dvd rom.

Or if you aren't worried about cost. muellers (sorry about the misspelllll.) endgame dvd's are fun to watch and play.

Flear's book Practical Endgame Play--Beyond the basics  is great to have as a reference, but I wouldn't start a systematic study of it until I had mastered the basics.

Endgame Strategy, Mikhail Shereshevsky.Good for understanding endgames in general.

Anybody has a link of any endgame book..including topic Opposition ??

Useful refernces thanks

A hearty second to that.  Another is Yuri Averbak's Endgame Series

Finally, John Nunn's Secrets of Rook Endings, Secrets of Pawnless Endings and Secrets of Minor-Piece Endings.

Download or use online Nalimov's endgame tablebases. 

Noone has mentioned this yet but:
there are two types of endgames concrete and well positons that are not quite endgames. Concrete is easy because you just learn them the key is that there are tons of them and you can feel very overwhelmed at times due to the amount of material. I would suggest getting Silman's book and use it as a guide for what you must know cold, 100% , zero mistakes for each level. Use the Dvoestky and Muller books with concrete positions to round out the chapters by Silman. 

I also really like Chess Endgame course by Rosen for this purpose. Its a highly underrated training book IMO.

The next category is the how to play positions that are not concrete. 
Mendis has some good stuff on middlegame to endgame

Chernev capablanca best endgames also falls into this idea of how to play from the middlegame to the endgame.

I believe Flear has a book on endgames that falls into this category as well.

Karpov endgame virtoso was mentioned and thats another good book so you can see how things are related.
