In his eight years with Golden Gryphon (1999–2007), Marty edited 23 1/2 hardcovers, 4 limited edition chapbooks, and 4 reprint trade paperbacks. The 1/2 title is the original anthology The Silver Gryphon (2003, marking the press's twenty-fifth hardcover), which he co-edited with publisher Gary Turner. The 23 titles include Charles Stross's Hugo winner novella "The Concrete Jungle" in The Atrocity Archives (2004), Jeffrey Ford's World Fantasy winners The Fantasy Writer's Assistant and Other Stories (2002) and novella "Botch Town" in The Empire of Ice Cream (2006), Lucius Shepard's International Horror Guild winner Louisiana Breakdown (2003), and M.

Marty now freelances, working directly with authors to prepare their manuscripts for publication, as well as working for independent publishers Night Shade and Tachyon, and other publishers including Ace (Charles Stross's "Laundry Files" series) and Morrigan UK (Liz Williams's "Detective Inspector Chen" series). He has also co-edited, with Claude Lalumière, the anthology of sardonic fiction Witpunk (Four Walls Eight Windows, 2003), and with Nick Gevers, original Fermi Paradox anthology Is Anybody Out There? (DAW, 2010). Marty's most recent project is Alien Contact (Night Shade, 2011), an anthology of the best alien contact stories from the past thirty or so years.
