http://www.scala-lang.org/node/2200"I found the book on Scala is a great read. I almost read it from cover to cover in one sitting, but it is not good for reference. The index is incomplete and so many of the language features are hard to find."
While i own the book myself ( haven't finished it yet, shame on me!), i concur that its nice introduction to
some but often i need to look up things on the net.
