Hello there,
I just discovered this imprint this month through Leigh Brackett's The Secret of Sinharat. THANK YOU so much for reprinting her so I could discover her! Seriously, most male authors past and present could learn a thing or two about hard-edged fiction from Brackett & Stark. I'm current reading Black God's Kiss and have Elak of Atlantis and Northwest of Earth on order. I've heard Kuttner and Moore's reps for years and its nice to finally try them out.
Anyways since this is the request thread, I'd figure I'd ask: Are any of the Zelazny novels you're looking at the Dilvish the Damned books? I remember reading the collection of his stories and the novel-length finale in a junior high school library and liking both nearly as much if not more so than the Amber books. I'd love to see them in print again in case my memory holds up.
Also, I love the idea of compiling an anthology of old sword & sorcery fiction. One thing I loved about the genre is the fact a lot of the adventures were done-in-one short stories before the character moved on. I don't know what specific authors you have in mind, but may I suggest the Ryre the Swordsman stories by Ramsey Campbell? I've never read them myself, but I'm more than familiar with his horror stories and would be interested in seeing something what the man's sword & sorcery fiction is like.
Also, I'm not too sure if the book is what you're looking for with Planet Stories, but do you have any interest in Fredric Brown's What Mad Universe? It seems like it would be a great romp delivering on the pulp thrills while ramping up the absurdity and humour.
In regards to the idea floated a while back about game stats for some of the books' characters and creatures, I'd like to also throw in my support for that. I don't really get a chance to game nowadays myself, but I know for a fact that I would not have sought out Leiber, Lovecraft, and Moorcock if I hadn't been exposed to their pantheons of gods and heroes in an old TSR Deities & Demigods book I picked up when I was 12. I'm sure a lot of gamers nowadays would have a similar experience if they picked up a stats book first.
Finally, if they're not too much of a hassle, could you please keep getting authors to write introductions to these books? Moorcock's introduction to Brackett's was delight, and I'm looking forward to seeing what Joe Lansdale has to say about Kuttner.
Keep up the good work!
