T HE FOURTH AND FINAL VOLUME of the current OED Supplement has now been published (1986). The editors attempted to include the widest possible coverage of Americanisms as well as other English words and expressions. Having contributed thousands of the earliest-appearance-inprint citations to all four volumes, I found that I had in my files many more that turned up after the final deadline. Indeed, there are too many at the present time for publication in any journal; complete publication must await the OED's planned computerization of the entire dictionary and the issuing of a revised edition. I offer here about a hundred antedatings of Americanisms which predate the OED Supplement or other dictionaries by at least thirty years. (One, for Garden of America, is 164 years prior to its earliest previous dating.) Where a word is absent from OED or one of its Supplements, I have taken the earliest date found in any other available source. Key to abbreviations: DAE = Dictionary of American English on Historical Principles, ed. Sir William Craigie, J.R. Hulbert, et al. (1936); DA = Dictionary of Americanisms on Historical Principles, ed. Mitford M. Mathews (1951); OED = Oxford English Dictionary; OEDS = 1932 Supplement; OEDS2 = current Supplement (1972-86). Square brackets around an antedate indicate that, while the printed source was later than the antedating, the printed source describes explicitly the earlier citation.
