Roger Elwood was a prolific editor of anthologies from the 1960s, when he co-edited several with Sam Moskowitz, through the mid-1970s, when he flooded the market with some four dozen original anthologies of varying quality. The photo shows 31 of the most significant, omitting reprint anthologies and some 15 original Young Adult anthologies. Those YA books, and many in the photo, were sold to publishers with little experiencing publishing SF, and the appearance of so many so quickly is thought to have saturated and thus spoiled the market. (Indeed, Harrison's Nova and Hoskins' Infinity did not survive the Elwood boom of 1973-74.)

Still, a number of these books were significant, and Elwood attracted both seasoned writers like Robert Silverberg (with "The Feast of St. Dionysus" and "Capricorn Games" among others), Poul Anderson, and Leigh Brackett, and new writers like R.A. Lafferty ("The World as Will and Wallpaper"), Barry N. Malzberg, and Gene Wolfe.

Elwood had strictures about depiction of sex and religion (he was a devout Christian), though several of these books have explicitly religious themes: Signs and Wonders, Flame Tree Planet, and Strange Gods. A World Name Cleopatra was a shared world anthology in the manner of Ellison's Medea and Silverberg's Murasaki. The four Continuum published eight story series, one episode in each volume, some by the same writer across all volumes, others continued by different writers. In the Wake of Man and Futurelove were three novella volumes. Six Science Fiction Plays published, for the first time, the original version of Harlan Ellison's Star Trek script "The City on the Edge of Forever." And Epoch, the largest volume and co-edited by Robert Silverberg, was an ambitious "state of the art" anthology that produced Hugo or Nebula nominated stories by Michael Bishop, Larry Niven, and Frederik Pohl. (Of all the other stories from these anthologies, only Farmer's in Omega and Monteleone's in Dystopian Visions were award nominees, both for the Nebula.)

The photo shows all but a couple of the 31 books compiled here, some of them in paperback or book club editions. (The paperback reprint of Savings Worlds was retitled The Wounded Planet.)

Most published authors in these books: Barry N. Malzberg (29), R.A. Lafferty (14), Gene Wolfe (11), Anne McCaffrey (9), then Poul Anderson, Philip Jose Farmer, Thomas N. Scortia, Robert Silverberg, and George Zebrowski (8 each).
