Size does not matter

This is a stack that won't be overflown soon (stack ... overflow ... get it ? ha ha) but this is the iOS Team's little stack of books. Sure we have great documentation from Apple and great apps (like Dash) to read this documentation but you know, once in a while, dead trees are more pleasant. Their lacks of twitter/fb/rss clients help to focus on the content :)

Our little library includes (some are actually borrowed, thus not showing):

• The Mathematical Theory of Communication
• Computers and Intractability
• Code Complete 2
• Advanced Mac OS X Programming
• Comprendre l'électronique
• Digital Watermarking
• Patterns of Enterprise Application Architecture
• iOS Programming: The Big Nerd Ranch Guide
• NSHipster: Obscure Topics in Cocoa & Objective-C
• CFHipsterRef: Low-Level Programming on iOS & Mac OS X
• Functional Reactive Programming on iOS
• Remote
• Joel On Software
• Effective Objective-C 2.0
• Android Programming: The Big Nerd Ranch Guide

We certainly are missing great things. Are there any you would recommend ?
