The Power of Illusion (2010) - the last collection of stories by "Christopher Anvil" (the name used by Harry C. Crosby for most of his fiction.) Eric Flint tells in his afterword that this collection completes the goal of having "back in print everything Anvil wrote in the way of science fiction." Baen Books printed this in Trade-paperback and mass-market paperback formats. The SFBC reprinted it in 2012 - the only hardcover edition.
