i think it was discussed a couple of years ago. basically steve jackson games wont release the copyright

(Can I) reprint some of your products that are out of print?
NO. Absolutely not. These games might be out of print, but they still belong to us, and we have to protect our rights and the rights of the creators. And it's quite likely that they might come back into print some day, in some form.

If you find one of our games online, in any format (PDF, HTML, text, or anything else), please notify our online enforcement team and we'll deal with it. We have never had to actually sue anybody to protect our rights online . . . dozens of people have infringed us, most have stopped when notified, and a small remainder (mostly people who didn't post contact info) have had their free web pages taken down by the provider. A lawsuit would be the last resort, but yes, we'd do it if we had to. Hopefully, we'll never have to.
