"When the complete edition of what would become the Oxford English Dictionary debuted in 1928, it was lauded as a comprehensive collection of the English language, a glossary so vast—and so thorough—that no other reference book could ever exceed its detail or depth. In total, the project took seven decades to catalogue everything from A to Z, defining a total of 414,825 words. But in the eyes of its editor James Murray, the very first volume of the dictionary was something of an embarrassment: It was missing a word.

Looking back, it’s impressive that more words were not lost. Assembling the OED was a nightmare. Before the first volume—an installment consisting of words beginning with the letters A and B—was published in 1888, multiple editors had taken (and abandoned) the helm, and each regime change created new opportunities for mayhem. When James Murray took command in 1879, the Oxford English Dictionary could best be defined by the word disarray."

This is an amazing story. I've not heard of the history of the OED and only owned the two volume Shorter OED years ago.
