Where to find the synthesizible set of Verilog

I like this document for starters: http://www.altera.com/literature/hb/qts/qts_qii51007.pdf

I learned verilog the wrong way and this book helped put me back on the right path: http://www.amazon.com/verilog-hdl-synthesis-practical-primer/dp/0965039153

So are you looking for what Quartus supports in terms of synthesizable code or are you looking for general information on this? You'll find that what Quartus II treats as synthesizable code is no different than most synthesis engines out there.
