@owenblacker First, thanks!
Secondly, don't think they're available. Gollancz talked about doing masterworks, which would have seen them reissued, but that was several years ago, and in the way of things in publishing nothing came of it.
@RussJonesWrites @EdinburghSFF Nothing to perhaps pennies, if it's sold through a supermarket at high discount under a publisher's net receipts clause.
@Andr6wMale The more complications you add the bulkier it gets, I guess. I'm always shocked by how ugly some of the really upper edge stuff is. As if you've thrown together a time piece from the button box, washer jar and bits of old girder for a mere ยฃ250,000.
