Research History
Mike Christie submitted a cite for the form "tri-dim" from a 1979 reprint of Robert Heinlein's "The Puppet Masters"; and also checked the 1951 first magazine appearance and determined that the word appears there as "tri-dimensional" instead. Malcolm Farmer verified the cite in a 1969 edition; we would like to check the 1951 first edition, or any other edition prior to 1963.
Katrina Campbell submitted a cite from a 1985 reprint of Edmond Hamilton's 1968 "The World of the Starwolves".
Ralf Brown located and Mike Christie submitted a 1963 cite from Robert Silverberg's "To See The Invisible Man".
