Once again in the horizons busting apart department, here's a thirty-plus collection of outside looking in, double talk, alien existence, explorations, super-normals, machines and minds, unknown territories..... The ladies are making the grade (three listed here); old pen pals are Heinlein, Leiber, Sturgeon, Asimov, Blish, Simak, Kornbluth (some having double entries); there's a real new look in the other authors for the undedicated. What an invasion!
