Here is the link.. I suspect that you have to have the "paid" subscription now to view any of their content, but I could be wrong!! (I have the paid subscription / download and read the PDFs on my big laptop, but it is a PITArse to carry around)

They (Wizards of the Coast) also have PDFs of their game books as well and if this PDF works, that would be a huge deal for us to carry around a device that weighs a few ounces vs 10 books!
And yes, I still play D&D...I am 38, married, own my own home, college degree, grad school, etc...nerds rule!!
