~~~ Edit - update on DndClassics.com ~~~
There's going to be an ongoing rollout of classic products.
Here's the email I got from OneBookShelf earlier this morning:
"Customers who purchased D&D titles from us in the past will be able to download the newly updated D&D PDFs for free in the My Library section of the My Account page as they are re-released by WotC.
There are over 80 titles available today and more on the way each month."
