If you haven't read any of his work, check this out. If you have, it's a good place to find the stories you may have missed, if you bought compilations.
Strange. You'd think there would be a lawsuit over this. Or maybe his stories are public domain? I would think someone would have control over the estate, such as it is.
No matter, I have it all in books anyways.

There is a bit of debate over the copyright issue, and the people in charge of the estate don't really care either way. The laws regarding the copyright are conflicting, and even using a strict ruling on them, alot of his work would be public domain now.
