I know not everyone reads chess books anymore, but I also know they can be a route to improvement for many players. It's also good to know what you liked about it, and a brief idea of what it is about. 

Bobby Fisher teaches chess & Chess Openings Theory and Practice

Basic Chess Endings - Rueben Fine  (my first endgame book, but it has many errors and is quite a dry read)

It may have been the way I used it rather than the book itself. I would setup the book position on my computer and attempt to figure out myself the solution/ending. Once I'd done that and experienced some of the problems with the ending, I would work my way through the text. Setting up the position on the computer again, I would attempt to navigate the new information. I would continue working through the text followed by attempting to apply the new information until I became comfortable with the position. After that it was on to the next position. I was unable to complete the book in this fashion as was my plan, but life happens sometimes altering things.

I bought and have been going through "Bobby Fischer Teaches Chess" and it's really opened my eyes to a lot of different principles so far, excited to check out some of these other recommendations. 

I'm currently starting Silman's Complete Endgame Course. After reading the Preface and Introduction, I believe it may have something for everyone regardless of playing level. 

I currently have the Kindle version of a couple of books by Cyrus Lakdawala -- London (Opening); Tactical Training; and Tactical Training in the End Game.  On improvement ... Step 3 Method by Rob Brunia and Cor van Wijgerden
