Dvoretsky's Endgame Manual, a book by Mark Dvoretsky, is probably the best endgame book of recent years. It has very in-depth analysis and examples, yet is not encyclopedic. There are fourteen chapters on how to handle different material balances, one on general ideas, and one on solutions. Dvoretsky highlights the essential knowledge in blue, and has the extra examples in black. There are also "Tragicomidies", which are examples of masters making simple mistakes, and then showing what they could have improved on. Overall, I think that you should read Silman's Endgame Manual for the basics, but this is a good supplement for advanced players.
