In 1857, work began on a revolutionary new dictionary covering the entire history of English word usage with example quotations. The first installment of A New English Dictionary on Historical Principles, covering A through Ant, appeared in 1884. The last, covering V-Z, was published in 1928. Its US copyright status has been murky, but as of tomorrow the entire first edition of what’s now known as the Oxford English Dictionary is definitively in the US public domain. #PublicDomainDayCountdown
