 **If you have time**
 - [ ] [Programming Pearls](http://www.amazon.com/Programming-Pearls-2nd-Jon-Bentley/dp/0201657880)
+    - The first couple of chapters present clever solutions to programming problems (some very old using data tape) but
+      that is just an intro. This a guidebook on program design and architecture, much like Code Complete, but much shorter.
 - [ ] [Algorithms and Programming: Problems and Solutions](http://www.amazon.com/Algorithms-Programming-Solutions-Alexander-Shen/dp/0817638474)
+- [ ] [Elements of Programming Interviews](https://www.amazon.com/Elements-Programming-Interviews-Insiders-Guide/dp/1479274836)
+    - all code is in C++, if you're looking to use C++ in your interview
+    - good book on problem solving in general.
+    
+**Perhaps**
 - [ ] [Introduction to Algorithms](https://www.amazon.com/Introduction-Algorithms-3rd-MIT-Press/dp/0262033844)
+    - **Important:** Reading this book will only have limited value. This book is a great review of algorithms and data
+     structures, but won't teach you how to write good code. You have to be able to code a decent solution efficiently.
     - To quote Yegge: "But if you want to come into your interviews *prepped*, then consider deferring your application until you've made your way through that book."
     - Half.com is a great resource for textbooks at good prices.
     - aka CLR, sometimes CLRS, because Stein was late to the game
