I just noticed on jw org they have a publication called the 2014 JW research guide. Browsing the topics, you can see it's the up to date doctrine.
One category for example is 'recreation and entertainment' and it's filled with gems referenced for research for jws, articles such as, "Keep leisure in it's proper place", "Why won't my parents let me have fun?", "Turn your eyes away from worthless things!", etc.
