Jim Baen was Editor-in-Chief and publisher of Baen Books, and renowned in the science fiction field for his taste and ability to select authors with strong storytelling ability and steer them to commercial success. Prior to founding of Baen Books, he was the editor of science fiction magazine Galaxy, science fiction editor of Ace Books, and an editor at Tor Books.
This is the seventh issue of Destinies, a science fiction magazine in mass-market paperback format that Baen established and edited for Ace Books until he left to direct his own eponymous science fiction/fantasy publishing company. The first four or five decades of the sf genre (from the first issue of Gernsback's Amazing Stories until around the time of Ellison's Dangerous Visions original anthology, give or take, more or less) were absolutely dominated by the magazines, first in pulp and then in digest-sized format. Destinies was an innovative concept that attempted to blend the best of both worlds, incorporating the less-ephemeral book format with the charm of original illustrations and columns that promoted a sense of community one found in the magazines. The authors were mostly from Baen's stable that he'd built at Ace (and his earlier stint as editor of Galaxy magazine) and ran a little heavy with his odd mix of pro-science conservative libertarianism, but he published some very good stuff. The non-fiction in this volume (listed as second issue of volume two) came from Jerry Pournelle, G. Harry Stine, an uncredited piece from the L-5 society, Frederik Pohl, Orson Card, Norman Spinrad, Charles Sheffield, James Gunn, and a brief Robert A. Heinlein excerpt from his Expanded Universe collection. There is good interior art from Alicia Austin, Stephen E. Fabian, Janet Aulisio, David Egge, Tom Broz, and Broeck Steadman, and a nice cover by Vincent Di Fate. It contained a short story by Sandra Koester, a cute "oddity" by Joe Haldeman, novelettes by Dean Ing and Joan Vinge, and a novella from Kevin Christensen which I remembered enjoying but mistakenly remembered as being written by Charles Sheffield. It's one of their weaker issues for fiction, but interesting overall.
