As Charles Rutledge points out in his tribute, his greatest contribution to the field was as an editor rather than an author. He was the editor of the 5 volume Swords Against Darkness series of original sword and sorcery anthologies. I’ve got all but volume 3 (with duplicates of 2 and 5). I was considering doing a series of posts looking at each one when I track down volume 3. That plan hasn’t changed with Mr. Offutt’s passing. I’ve also got one or two of his novels around here somewhere I intend to read at some point.
Even though he hasn’t been active in sword and sorcery circles for a number of years (at least not that I know of), we’ve lost one of the major players from the sword and sorcery boom from the 70s.
