This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
There's a separate site called SOABooks which is dedicated for those books. And of course there are many articles you can find by a simple search where you can learn the basics. Also you can various pointers and recommendations in our FAQ section.
