There seem to be quite a few new titles in the sword and sorcery tradition, thanks to indie publishers who are specializing in sword and sorcery and fantasy adventure tales. I haven't read any of these, so let me know how they are.
I just read a review of one at Black Gate.

DMR Books published quite a few sword and sorcery titles in the Kindle store (and probably elsewhere as well). For example, their Renegade Swords anthology includes Robert E. Howard and Lin Carter but also Richard L. Tierney. (Tierney co-wrote some Red Sonja paperbacks in the 1980s that are sadly out of print.) Their "Heroes of Atlantis & Lemuria" reprints stories by Manly Wade Wellman, Leigh Bracket, and others. They've also reprinted "Swordsmen from the Stars," a fantasy novel by Poul Anderson, and they're printing some newer works as well, such as "Necromancy in Nilztiria" by D. M. Ritzlin.
Pulp Hero Press also has a number of sword and sorcery titles, such as Savage Scrolls [Volume One]: Thrilling Tales of Sword-and-Sorcery.
Also, look for Savage Realms Monthly, a continuing anthology of "dark fantasy and sword and sorcery short adventure stories." (This is put out by Literary Rebel, LLC.) And Swords & Sorceries: Tales of Heroic Fantasy (put out by Parallel Universe Publications).
For a recent nonfiction book on the topic, check out "Flame and Crimson: A History of Sword-and-Sorcery" from Pulp Hero Press. (There are also some newer books about Robert E. Howard and Conan, although many of the specialized ones are available in print only.)
