Silman's Complete endgame course is great, and Rook Endings by Grigory Levenfish and Vasily Smyslov will turn you into an expert at rook endings.

Silman's Complete endgame course is a great book that will take you as far as you feel like going from the very beginning on up to master level.

Thanks for the link: I'd recommend it: great site for players of all levels! [I am assuming that the lines given are mostly correct :)]
So it seems like every intermediate and advanced chess player agrees that the endgame needs just as much if not more study as openings and middle games. I'm relatively new to chess, about 6 months in and I feel I have an understanding of solid opening and middle games; but I often get in endgames where I have absolutely no clue what to do.
What are some good books/online sources/etc. that I could use to help improve my endgame?
