| Comment | Enoch Forrester submitted a cite from a 1987 reprint of Robert Heinlein's "Starship Troopers"; we would like to check the 1959 first edition. Enoch Forrester submitted a cite from Joe Haldeman's "The Forever War"; Mike Christie verified it in the 1975 first magazine appearance. John Groth submitted a cite from a 2000 reprint of Robert Heinlein's "Gulf" in "Assignment in Eternity". Mike Christie checked the 1949 magazine version and the phrase "nova bomb" is not used there; however Rick Hauptmann verified the cite in the 1953 first book edition. Edward Bornstein submitted a 1975 cite from "Voyage to a Forgotten Sun" by Donald J. Pfeil In addition to any antedatings, we would like cites of any date from other authors. |
