When I learn something, I would like to simultaneously read several books on the same topic, so that I could learn same things from different perspective. It works great for me when I learn Haskell, Scala, and other things. Here is the list of materials I used to learn Haskell: 1. LYAH, http://learnyouahaskell.com/ http://learnyouahaskell.com/ 2. Real world Haskell: http://book.realworldhaskell.org/read/ http://book.realworldhaskell.org/read/ 3. Programming in Haskell: http://www.amazon.com/Programming-Haskell-Graham-Hutton/dp/0521692695 http://www.amazon.com/Programming-Haskell-Graham-Hutton/dp/0... (No one suggests this book, but I do think this book is well-written and concise.) 4.
