Books: Galactic Empires, Addendum

-Might be worth noting, for the curious, that these two volumes are part of a longer series of anthologies edited by Aldiss, known collectively as the "Space Opera" series. The titles are Space Opera, Space Odysseys, Evil Earths, Galactic Empires Volume One, Galactic Empires Volume Two, and Perilous Planets. (I own Space Opera and the two GE ones.)
